These steps work with Microsoft Excel 97. Start Microsoft Excel and open the file you want to change. Open the When menu and select All. Open the Who menu and select Everyone. Enter your new changes.
Changed cells have a triangle in the left corner.
All the changes in a file will be tracked. Selecting Everyone in the Who menu will make your file shared. Select the option later to see the changes you made. Open the Tools menu and Track Changes menu and select Accept and Reject Changes option. In the Accept or Reject Changes dialog box, review the edits to the spreadsheet.
