How to Turn on Change Tracking in Excel 2013 Workbooks
(Optional) If you want to restrict change tracking, click the name of the person to whom you want to restrict change tracking in the Who drop-down menu.
Note that selecting any option from the Who drop-down menu automatically selects the Who check box by putting a check mark in it.
By default, changes made to any and all cells in every sheet in the workbook are tracked. To restrict the change tracking to a particular range or nonadjacent cell selection, select the Where check box and then select the cells.
