Merging copies of a shared workbook

Turning on the Track Changes feature automatically shares your workbook. When multiple users collaborate on the same shared workbook, you can use the Compare and Merge Workbooks command to view all of their changes at once and address them by accepting or rejecting them.

Each person you collaborate with must save a copy of the shared workbook using a unique file name that differs from the original. For example, if the original file name is Agenda, your collaborators could use the files names Agenda—Ana's Changes or David Agenda Feedback.

You can only merge copies of the same shared workbook. All of the copies you plan to merge should be located in the same folder.
