7 Page 7 - Excel Advanced Level Manual Course Basics Toolbars The Title Bar The title bar is displayed along the top of almost all program, folder and dialog box windows. It is used to display information such as the name of the application (or folder) and the document you are working on. Information which is displayed here may vary. The example shown illustrates the title bar for a program called Microsoft Word, in which a document called Document1 has been opened or saved: The Menu Bar The menu bar is located under the title bar, and contains a series of drop down menus. The example shown illustrates the Microsoft Word Menu Bar: To execute Menu commands In most cases, you are asked to use the mouse to execute a series of menu commands (e.g., File > Save As). What this means is that you select File from the main menu, followed by Save As:

8 Page 8 - Excel Advanced Level Manual The Tool Bar The tool bar contains a series of icons, which allow you to achieve a desired effect as quickly as possible. In the example shown, taken from the Microsoft Word Formatting toolbar, to make the selected text bold, you would click on the Bold icon: Installing the Sample Files Use Windows Explorer to create a folder called Excel 2003 Advanced Samples, in the My Documents folder. If you are installing the sample files from the CD-ROM, place the CD-ROM in the CD drive and copy the files from the excel_2003_advanced_usa\exercise_files to the My Documents\Excel 2003 Advanced Samples folder. If these files have been copied to your network server, then ask your trainer/supervisor for more information about how to copy these files to your PC s hard disk. Notes for tutors: The above instructions are for Windows that has not been set-up for a multiuser environment (with individual profiles). The instructions above may require modification within a Windows mutliuser environment. Where possible preinstall the relevant work files prior to use by students/delegates.

9 Page 9 - Excel Advanced Level Manual Importing Data When you have completed this learning module you will have seen how to: Import data from external sources Import data into Excel Import text files into Excel Import text using the Text Import Wizard Refresh data from imported text files Use Microsoft Query Add a data source Create a Query Query data from the Web Access the New Web Query dialog box Create a new Web Query Save a Web Query Set Web Query options Run a saved Web Query Refresh a Web Query Refresh external data without losing the formatting Refresh external data automatically Importing Data from External Sources Using Database Terminology In a corporate environment, data is not usually created and stored within Excel, but may be stored on mainframes or database servers. Commonly used programs include Access, dbase, FoxPro, Paradox, Oracle, or SQL Server. To import data from a database, it is useful to understand the following common database terminology: Data Sources: The data source informs the ODBC Manager about the type of data being used and its location. Microsoft Query: A stand-alone program supplied with Microsoft Excel. It acts as an interface, allowing you to create queries that are translated into SQL format. ODBC: It stands for Open Database Connectivity, and is a term used to describe an industry standard used to connect cross-platform databases.

10 Page 10 - Excel Advanced Level Manual ODBC Add-in: It allows Excel to communicate with the ODBC Manager directly (without using the Microsoft Query as an intermediary). It also provides the SQL.REQUEST worksheet function, as well as providing an Application Programmers Interface (API) for application developers. ODBC Driver: The ODBC Manager uses the ODBC driver as an intermediate step. ODBC drivers supplied with Excel include Access, dbase, FoxPro, Paradox, SQL Server, Oracle, Excel Worksheets, and text files. ODBC Manager: This is a Microsoft derived technology that allows programs such as Excel and Microsoft Query to interface with a range of different databases. When you perform a Microsoft query, an SQL statement is sent to the ODBC Manager. The ODBC Manager then acts as an intermediary between the application and the database. This has the advantage that the same query may be used to access different database servers, including SQL Server, Oracle, dbase or Paradox. Structured Query Language (SQL): An industry standard language used for database communication. Excel queries using Microsoft Query use SQL behind the scenes. Importing Data into Excel You can import data using the following methods: Open command: From the main menu, choose File > Open to display the Open dialog box, and select the data file type from the File of type dropdown list. You can choose from the following types of file: Access, Lotus 1-2-3, Quattro Pro, Microsoft Works, dbase, SYLK, Data Interchange Format (DIF), All Web Pages, XML, and previous versions of Excel. The selected file will be translated by Excel and imported as an Excel spreadsheet. Export data into text files: From the database application where your data is stored, you can usually export the data you want into text files. You can then import these text files using the Text Import Wizard. Microsoft Query: This program is shipped with Microsoft Excel, and is an excellent tool for querying an external database. Queries allow you to specify the exact data you want from the external database. Web Queries: Microsoft Excel 2003 allows you to query and refresh data from the Internet. XML: Microsoft Excel 2003 now allows you to import XML files and map out individual elements to specified cells in a Worksheet. However, this added feature is only available in the Professional Edition of Office 2003, and not other

11 Page 11 - Excel Advanced Level Manual versions of Office. (If you are not sure which Office edition you are currently using, ask your instructor for assistance). Pivot Tables: Pivot Tables are useful for accessing and integrating external databases into Excel. They will be covered in chapter 3 of this manual. Importing Text Files Importing text files into Excel You can import text from other sources, saving the need to re-enter the data. To import text into Excel, it must be in a format that can be recognized by Excel. File formats are supported by Excel Text: Text files are plain text with no formatting information except line returns. Usually this file type contains one record of information per line, but the means of identifying the fields in a record varies. Text (Tab Delimited): With this text file format, tabs are used to identify fields in a record. Formatted Text: Formatted text files make use of position to define fields; each field starts at a defined position on the line. You may find this field type also referred to as Space Delimited, Fixed Width, or Column Delimited. Comma Separated Values (CSV): Commas are used by CSV text files to delimit (separate) fields. Although these files are called Comma Separated Values text files, commas are not always used as the delimiter. Examples of other delimiters include vertical bars ( ) and at signs (@). Note: If the text to be imported is not in recognized by Excel, Excel will launch the Text Wizard to provide assistance. Importing text using the Text Import Wizard The Text Import Wizard is a set of dialog boxes that guide you through the customization of imported text. From the main menu, choose File > Open to display the Open dialog box. From the Files of type dropdown list, select Text Files (*.prn, *.txt, *.csv). Select the file you want to open.

12 Page 12 - Excel Advanced Level Manual Click Open to display the Text Import Wizard - Step 1 of 3 dialog box: Excel will analyze the selected text file, and determine the file's data type, and display a preview of the data to be imported. In the above example, Excel determined the file to be a Delimited file. You can choose to alter the file type selection as needed. If your file contains header rows that you do not want imported, you can change the Start import at row number to exclude the header rows. When you change the Start import at row number, the preview will be updated to reflect the change. When you are satisfied with the options selected, click on the Next button to continue to the Text Import Wizard - Step 2 of 3 dialog box. Note: You can always use the Back button to go back to the previous dialog box and revise the options:

13 Page 13 - Excel Advanced Level Manual From this dialog box, you can set the delimiters your data contains--choose the type of Delimiters, select to Treat consecutive delimiters as one, and define the Text qualifier. The Data preview will display the data based on your choices. When you are satisfied with the options selected, click on the Next button to continue to the Text Import Wizard - Step 3 of 3 dialog box. Note: You can always use the Back button to go back to the previous dialog boxes and revise the options: From this dialog box, you can determine the data format of each column by selecting each column in the Data preview area and selecting its Column data format. If you do not want to import one of the columns, click on the column in the Data preview area, and select the Do not import column (skip) radio button in the Column data format area. When you are satisfied with the options selected, click on the Finish button to import the text into Excel. Note: You can always use the Back button to go back to previous dialog boxes and revise the options. Alternatively, you can click Cancel to close the wizard without importing the data:

From the main menu, choose Data > Refresh Data OR from the External Data toolbar, click on the Refresh Data display the Import Text File dialog box. icon to Select the text file you want. Click Import. Using Microsoft Query Adding a Data Source Microsoft Query allows you to obtain data from an external database. You can use the wizard to create filters and define sort order of data from an external database. Since Microsoft Query is a stand-alone program, it can be started independently; however, you can run Microsoft Query from within Excel. For illustrations purposes, we will run a query with the NorthWind Traders database, which is a sample database supplied with Microsoft Access. Make sure that Microsoft Query is installed. From the main menu, choose Data > Import External Data > New Database Query to display the Choose Data Source dialog box: Click on the Databases tab. With <New Data Source> selected, click OK to display the Create New Data Source dialog box:

27 Page 27 - Excel Advanced Level Manual Templates and Styles When you have completed this learning module you will have seen how to: Create a template Use templates Create a style Use styles Edit a style Delete a style Copy styles from another Workbook Working with Templates Using Templates When working with spreadsheets, you may wish to use the same layout or design. Instead of re-creating the design, you can create a template. Templates have the.xlt file extension, and can contain layout and formatting information, including text and graphics, layouts and styles, headers and footers, formulas, and macros. When templates are used to create a new Workbook, a copy is made, leaving the original template file intact for further use. Creating a Template Create a Workbook that contains all layout and formatting elements you want in your template. From the main menu, choose File > Save As to display the Save As dialog box. In the File name dropdown list box, type a template name. From the Save as type dropdown list box, select Template (*.XLT) to display the existing templates in the default Templates folder and add the.xlt extension to the file name:

28 Page 28 - Excel Advanced Level Manual Click Save to save the template in the Templates folder. Applying Templates From the main menu, choose File > New to display the New Workbook pane. From the Template section of the New Workbook pane, click on the blue On my computer link to display the Templates dialog box: Click on the General or the Spreadsheet Solutions tab to locate the template you want. For the default template, click on the General tab and select the Workbook icon. Click OK. Note: Excel 2003 allows you to access additional templates on the Microsoft Office website (Note: internet access is required to use this feature). Simply click on the Templates on Office Online link in the New Workbook pane, and you will be directed to the Office website, where you can search for the template you need. Experiment!

29 Page 29 - Excel Advanced Level Manual Working with Styles Using Styles Whereas a template is a collection of layout and formatting information for a workbook, a style is a collection of formatting information for a cell. Styles can contain formatting information, including Number, Font, Alignment, Border, Patterns, and Protection. You can use styles to reapply pre-defined formatting to multiple cells. When styles are used to format cells, you can reformat the Worksheet by modifying the styles. It is possible to copy styles from one Workbook to another. Excel 2003 comes with a number of pre-defined styles. By default, all cells are assigned the Normal style. Creating a Style Select the cell that contains the formatting you want in your style. From the main menu, choose Format > Style to display the Style dialog box. In the Style name dropdown list box, type a style name. Select the attributes (Number, Alignment, Font, Border, Patterns, and Protection) you want to include in the new style: Click Add to create the style Click OK to closes the Style dialog box.

32 Page 32 - Excel Advanced Level Manual Analyzing Data When you have completed this learning module you will have seen how to: Use Goal Seek Use a Data Table Create a one-variable Data Table Create a two-variable Data Table Speed up calculations with Data Tables Use Scenario Manager Add a scenario Show a scenario Delete a scenario Edit an existing scenario Summarize scenarios Use Solver Install Solver Change a constraint Delete a constraint Understand Pivot Tables Create Pivot Tables Drop data into Pivot Tables Modify data and refresh Pivot Tables Group data within Pivot Tables What-If Analysis Using What-If Analysis Excel provides a number of tools to help you find answers to "What-If" type questions. What-If Analysis allows you to see the effect that input value changes have on the result of the formulas. For example, what happens to a car loan payment if you reduced the down payment or increased the interest rate? Excel provides the following What-If Analysis tools: Goal Seek: Allows you to find the correct input to produce the desired outcome. Simple to use, but limited in power and flexibility. Data Tables: Allows you to see how the results are affected by changes in the input values displayed in a table. Simple to use, but limited in power and flexibility.

33 Page 33 - Excel Advanced Level Manual Scenario Manager: Allows you to create, manipulate, and save a number of different scenarios that use different input variables, producing different results. Simple to use, but limited in power and flexibility. Solver: Allows you to find the best solution to complex problems that revolve around the manipulation of multiple variables and constraints. More difficult to use, but very powerful and extremely flexible. Goal Seek Using Goal Seek Sometime when you are analyzing a problem, you know the end result you want to achieve, but want to determine the input values to achieve this result. The Goal Seek command will allow us to accomplish this easily. Goal seeking is the means to say, "This is the final value that I want to achieve, what input value do I need?" Excel calculates the input value needed by varying the value in the formula until the result is achieved. Applying Goal Seek Build a formula using cell references for each variable of your formula. The following example shows a simple calculation of the Price of car you can afford. The formula in cell B3 is: =(B1+B2)/0.2 Select the cell containing the formula for which you have an end result to achieve. In our example, select cell B3. From the main menu, choose Tools > Goal Seek to display the Goal Seek dialog box. The cell reference for the selected cell will appear in the Set cell text box. In the To value text box, enter the end result you want to achieve. In our example, we want to purchase a more expensive car; enter In the By changing cell text box, enter the cell containing the input value that you want changed to achieve the end result. In our example, we want to know

34 Page 34 - Excel Advanced Level Manual what Down payment is required. Click on cell B1: Click OK to run the Goal Seek. When the Goal Seek is complete, the Goal Seek Status dialog box will appear, and the results are reflected in the Worksheet: Click OK to accept the new values. Click Cancel to close the Goal Seek Status dialog box and leave the values unchanged. Data Tables Using Data Tables You can use Data Tables to calculate and compare the outcome of different inputs of a formula. The different combinations of input values and results are presented in a table format for easy comparison. Depending on your needs, you can change one or two variables in Data Tables.

35 Page 35 - Excel Advanced Level Manual Creating a one-variable Data Table A one-variable Data Table allows you to see the effects of changing one variable (input value) of a formula. In the following example, we will find out the effect the Down Payment has on the monthly Payments. Begin by designing the Worksheet with your initial input values. The input value that you want varied is referred to as the Input Cell. In our example, the Input Cell is B3. Create the Data Table by listing the substitution values of your Input Cell together, either in a column or in a row. In our example, we will list the substitution values in range C3:C6. Enter the formula, using the Input Cell in the formula, as follows: If your substitution values are column-oriented, enter the formula in the cell that is one column to the right and one cell above the first substitution value. In our example, the first substitution value is in cell C3 so we will enter the formula in cell D2. If your substitution values are row-oriented, enter the formula in the cell that is one row below and one cell to the left of the first substitution value. For example, if your first substitution value were in cell C3, then you would enter your formula in cell B4. Select a cell range that includes the formula and all the substitution values. In our example, the selected range is C2:D6: From the main menu, choose, Data > Table to display the Table dialog box: If your Data Table is column-oriented, in the Column input cell, enter the cell reference for the Input Cell. In our example, the Input Cell is B3. If your Data Table is row-oriented, in the Row input cell, enter the cell

36 Page 36 - Excel Advanced Level Manual reference for the Input Cell. Click OK to create the one-variable Data Table: Creating a two-variable Data Table A two-variable Data Table allows you to see the effects of changing two variables (input values) of a formula. In the following example, you will find the effects the Down Payment and the interest rate have on the monthly Payments. Begin by designing the Worksheet with your initial input values. The input values that you want varied are referred to as the Input Cells. In our example, the Input Cells are B3 and B5. Create the Data Table by entering your formula, using both Input Cells in your formula, in a cell that will define the top-left corner of your Data Table. In our example, we will enter the formula in cell C2. List the substitution values of your first Input Cell down a column to the below your formula. In our example, we will list the Down Payment substitution values in cell range C3:C6. List the substitution values of your second Input Cell across in a row to the right of your formula. In our example, we will list the Interest Rate substitution values in cell range D2:G2. Select a cell range that includes the formula and all the substitution values. In our example, the selected range is C2:G6: From the main menu, choose, Data > Table to display the Table dialog box:

37 Page 37 - Excel Advanced Level Manual In the Row input cell, enter the cell reference for the row Input Cell. In our example, the row Input Cell is B5. In the Column input cell, enter the cell reference for the column Input Cell. In our example, the column Input Cell is B3. Click OK to create the two-variable Data Table: Speeding up calculations with Data Tables By default, Excel will recalculate Data Tables every time the Worksheet requires recalculation, slowing your calculations. You can adjust this option, such that Data Tables are not automatically recalculated with the Worksheet. From the main menu, choose Tools > Options to display the Options dialog box, and click on the Calculation tab. Select the Automatic except tables radio button: Click OK. Scenario Manager

38 Page 38 - Excel Advanced Level Manual Using Scenario Manager In analyzing your data, you will frequently want to look at a number of differing options within your spreadsheet. Scenario Manager allows you to change multiple cells in order to see the effect of the changes, and keep your scenarios for review later. Scenarios are useful in forecasting the results of models, and can be printed in summary form. For example, we can use Scenario Manager to see the changes in total expenditures depending on scenarios that affect expense items differently. Adding a Scenario Begin by creating the initial scenario using our best guess on the percentage increases: Select the cells containing values that will change with different scenarios. In our example, select cell range C2:C5. From the main menu, choose Tools > Scenarios to display the Scenario Manager dialog box. (Notice that no scenarios have been defined): Click on the Add button to display the Add Scenario dialog box. In our example, we will create a scenario for Low Inflation, where the expected percentage increases are as follows: Rent - 1%, Staff - 2.5%, Energy - 10%,

39 Page 39 - Excel Advanced Level Manual and Other - 2%: In the Scenario name text box, enter a name for the scenario you are about to create. In this case, enter the name Low Inflation. Click OK to display the Scenario Values dialog box: Change the value in text box 1 to 1, change the value in text box 2 to 2.5, change the value in text box 3 to 10, and change the value in text box 4 to 2: Click OK to add the scenario and return to the Scenario Manager dialog box. (Notice that 'Low Inflation' is now listed in the Scenarios list box):

Click Close to close the Scenario Manager dialog box. Editing an existing Scenario From the main menu, choose Tools > Scenarios to display the Scenario Manager dialog box. From the Scenarios list box, select the scenario you want to edit. Click on the Edit button to display the Edit Scenario dialog box. (Notice that Excel automatically adds a 'Modified' message in the Comment text area): Click OK to display the Scenario Values dialog box: Make the changes you want. Click OK to add the scenario and return to the Scenario Manager dialog box. Click Close to close the Scenario Manager dialog box.

42 Page 42 - Excel Advanced Level Manual Summarizing Scenarios From the main menu, choose Tools > Scenarios to display the Scenario Manager dialog box. Click on the Summary button to display the Scenario Summary dialog box: Select the Scenario summary radio button. In the Result cells text box, enter the cell or range of the values you want to see in the summary. In our example, we will enter cell D6 to display the total estimated cost for next year. Click OK to display the summary in a new Worksheet: Solver Using Solver Solver is the most versatile What-if Analysis tool. It can handle many different variables, and where possible, Solver will produce the optimum answer. In order to understand Solver, you will need to know the following terms: Target Cell: The cell that will be set to a value, maximum or minimum. Often this cell is where you specify the maximum cost of a project. Adjustable Cell: The cells that Solver will change the contents of to achieve the desired objective.

43 Page 43 - Excel Advanced Level Manual Constraints: Contains the restrictions that Excel must observe. For example, we can use Solver to figure out the optimal combination of cars we should purchase based on budget and other constraints. Installing Solver By default, Solver is not installed with the basic Excel installation. If Solver is installed, it is listed under the Tools menu. If Solver is not listed, you can install it easily. From the main menu, choose Tools > Add-Ins to display the Add-Ins dialog box: Select the Solver Add-in checkbox. Click OK to install. Applying Solver Begin by constructing a Worksheet with the data you want Solver to use. In the following example, we have a budget of $500,000 to purchase as many new cars as possible for the new company car fleet. We need a mix of small, medium, and large cars:

44 Page 44 - Excel Advanced Level Manual Select the Target Cell. In our example, select cell D8. From the main menu, choose Tools > Solver to display the Solver Parameters dialog box. (Notice that the Set Target Cell text box contains cell reference $D$8): In the Equal To area, set the Max, Min, or Value of constraint by selecting the appropriate radio button, and entering the value into the text box. In our example, we will select Value of and enter in the text box to set the budget constraint. In the By Changing Cells area, select the cell(s) that we want to change to meet our target. In our example, we will be changing the numbers of cars in each class; select cell range C4:C6. Note: If you are not sure which cells to select, click on the Guess button, and Excel will suggest a range based on your worksheet. In the Subject to the Constraints area, click on the Add button to display the Add Constraint dialog box. In the Cell Reference text box, select the cell that the constraint will be applied to. In the dropdown list, select the operand you want. In the Constraint text box, enter a value or cell reference. For our example, to enter the budget constraint of $500,000, we will use $D$8 as the cell reference, select the <= (less than or equal to) operand, and enter as the constrained value:

45 Page 45 - Excel Advanced Level Manual Click OK to return to the Solver Parameters dialog box OR click Add to add another constraint. When you are satisfied with your Solver Parameters, click Solve. After a short time you will see the Solver Results dialog box: Select the Keep Solver Solution or Restore Original Values radio button. Click OK to apply your choice. In our example, the worksheet will appear as follows: (You may notice that the solution suggests the purchase of part of a car. You can create another constraint to force Excel to solve for whole number only): Changing a Constraint From the Solver Parameters dialog box, select a constraint you want to modify. Click on the Change button to display the Change Constraint dialog box:

46 Page 46 - Excel Advanced Level Manual Make the changes you want. Click OK to return to the Solver Parameters. Deleting a Constraint From the Solver Parameters dialog box, select a constraint you want to delete. Click on the Delete button. Using Pivot Tables Understanding Pivot Tables As the name suggests, a Pivot Table is simply a table of data, but has the advantage of allowing you to summarize fields in different dimensions. They seem difficult at first, but the best way to get used to them is to use a pivot table and experiment! The example below uses a table containing information relating to sales for a company that is selling training courses. By using a Pivot Table we could easily extract and summarize information from this table. Creating Pivot Tables Open the workbook containing the data from which you wish to create your pivot table:

47 Page 47 - Excel Advanced Level Manual Click within the body of the data and then click on the Data drop down menu and select the PivotTable and PivotChart Report command. This will display a wizard. In step one of the PivotTable and PivotChart Wizard, you can specify where the data is located and what type of report you wish to create. In this case accept the default offered: Click on the Next button to continue. This will display the next page of the wizard. Step two of the wizard allows you to specify the exact data that you wish to use. Again accept the default offered: Clicking on the Finish button will create your pivot table. Dropping data into Pivot Tables Now examine the Pivot Table you have just created. (As you can see in the illustration below, the Pivot Table toolbar is displayed by default):

48 Page 48 - Excel Advanced Level Manual As you can see in the illustration above, the Pivot Table Field List pane is also launched automatically when you create your Pivot Table. To begin creating your Pivot Table, simply drag and drop items from the Pivot Table Field List pane to the table. The following example will illustrate this feature: From within the Pivot Table task pane, click on the Sales Person field, and drag it into the part of the Pivot Table labeled Drop Row Fields Here. From within the Pivot Table task pane, click on the Customer field, and drag it into the part of the Pivot Table labeled Drop Column Fields Here. From within the Pivot Table task pane, click on the Total Value field, and drag it into the part of the Pivot Table labeled Drop Data Items Here. When you have finished, the table should be as illustrated. As you can see a very easy way of extracting and summarizing data!: Modifying data and refreshing Pivot Tables Following on from our previous example, you will notice that the Pivot Table was created on a new worksheet, within your Excel worksheet.

49 Page 49 - Excel Advanced Level Manual In this example, the Pivot Table is located on the Sheet1 Worksheet, while the original Worksheet that the table is based on is located in the Pivot Table Data Worksheet. Click on the Pivot Table Data Worksheet tab: Make some changes, such as in this case change the value within cell D4, which we have changed from 1 to 10: Click on the Sheet1 tab, which contains the Pivot Table, and you will notice that the Pivot Table has not been updated to take account of your changed data: If you click on the Refresh Data icon (within the Pivot Table toolbar), you will see the data change, as illustrated:

50 Page 50 - Excel Advanced Level Manual Grouping data within Pivot Tables Following on from the previous example, let's say that Lou and Sue are working together as a team, and we want to group their sales together. First we need to click on cell A5 (the cell containing the text Lou). While depressing the Ctrl key we then need to click on cell A8 (the cell containing the text Sue). When you release the Ctrl key, both cells should remain selected. Right click over the selected cells and from the popup menu displayed select the Group and Show Detail command. From the submenu displayed select Group: The screen will then change to display the grouped results, as illustrated: Review Questions How would you: Use Goal Seek? Use a Data Table?

From the Select Files to Merge into Current Workbook dialog box, select the file(s) you want. (Hold down the Ctrl key to select more than one file): Click OK. Note: Changes to the merged Workbook are identified with comments: Sending Workbooks Sending Workbooks for Review You can use Excel to send your Workbook to other people for review and comment. Begin by opening the Workbook you want to send. From the main menu, choose File > Send to > Mail Recipient (for Review). This brings up a new message with the Workbook attached from your default program:

95 Page 95 - Excel Advanced Level Manual Enter the recipients you want to include. Customize your subject and message. Click Send.

To view the message, reviewers will need an program that supports HTML.

96 Page 96 - Excel Advanced Level Manual Routing a Workbook When you send a Workbook for review, each mail recipient receives their own copy of the message and Workbook. This requires you to merge their comments and changes at the end of the review. Alternatively, you can route a Workbook. With routing, only one copy of the Workbook is passed from recipient to recipient. In order for this function to work, all recipients must use Microsoft Outlook as their program. While the Workbook is being routed, you can keep track of its progress. At the end of the routing, the Workbook, with its changes, is returned to you. Begin by opening the Workbook you want to send. From the main menu, choose File > Send to > Routing Recipient. Enter the routing recipients you want to include. Customize your subject and message. Click OK.

From the main menu, choose File > Send to > Next Routing Recipient. Click OK. Consolidation Consolidating Consolidation allows you to select blocks of data from several different Worksheets, or different pages of the same Workbook, and combine their values into a single, summary range in a Workbook. This feature is easier than copying data from several Worksheets and then pasting the data into a single Worksheet. For example, you have a Workbook that contains sales figures for each quarter on a different Worksheet, and you want to create an annual summary. You can use Data Consolidation to consolidate the sales figures.
