Excel allows multiple people to access a workbook at the same time, if desired. This can be very handy when a workbook is in active use or development, and there are multiple people in your department who all have a hand in the process. You can share a workbook in this way:
- Load the workbook you want to share.
- Display the Review tab of the ribbon.
- Click the Share Workbook tool, in the Changes group. Excel displays the Share Workbook dialog box. (See Figure 1.)
- Choose the Allow Changes check box.
- Click on OK.

This is the simplest way to share access to a workbook. There are other options available in the Share Workbook dialog box that should be examined, however. Notice that the dialog box also lists the users currently accessing the current workbook. It should go without saying that when you first share a workbook, you are the only user that will be listed in the dialog box. However, if you again display the Share Workbook dialog box at a later time (such as when you are thinking of turning sharing off), there could easily be multiple users listed.
Notice, as well, that the Share Workbook dialog box also contains an Advanced tab. This tab is where you can specify how changes should be handled by Excel.
The whole idea behind sharing a workbook among multiple users is that Excel tracks any changes made and then at a later date you merge together everyone’s work. The Advanced tab is where you indicate how you want Excel to prepare for this future time. Here you can specify how changes should be tracked, when changes should be updated, and what to do if Excel detects a conflict between changes specified by two or more users.
