A new feature debuting in Microsoft 365 Excel. If you save your file to OneDrive Excel will record every change anyone types in the workbook. You can then see those changes using Review, Show Changes, in Excel Online. It is tracking the changes anyone is making in Win32 Excel. This is HUGE!
I learned that the changes are kept for 60 days. Here is the Microsoft article on the feature: https://support.microsoft.com/en-us/office/get-help-with-show-changes-in-excel-a1493bf9-25c3-470a-b970-60eceb0136e5
