Embedding Your Phone Number in a Workbook

Excel is used quite extensively in corporate environments. It is often desirable to know exactly who created a workbook, particularly if it has been months since a workbook was last reviewed. Excel keeps track of non-workbook data that can be used to help identify an author. One piece of data that could be very helpful is the phone number of the workbook's author. To specify a phone number, follow these steps:

1. Choose Properties from the File menu. Excel displays the workbook's Properties dialog box. (To display the Properties dialog box in Excel 2007, click the Office button | Prepare | Properties. This displays an abbreviated set of properties just above your worksheet; click the down-arrow next to Document Properties and choose Advanced Properties.)
2. Make sure the Custom tab is selected. (Click here to see a related figure.)
3. In the list of properties at the top of the dialog box (listed in the Name control), choose Telephone Number.
4. In the Value box, enter the phone number you want associated with the workbook.
5. Click on Add.
6. Click on OK.
