This feature allows you to make an Excel file that tells everyone that it is the final version, the completed version.
This is great when you need to send a file to someone while at the same time letting them know that no further changes need to or should be made to the workbook.
Note: this feature does not prevent a user from making changes to the workbook. It merely informs them that no further changes need to be made.
The next time you, or anyone else, open the file, a notification message will appear at the top of the window:
If the user then clicks Edit Anyway and edits and saves the file, it will no longer be marked as final.
I just want to repeat that this feature does not prevent the editing of a workbook. It merely tells someone that this is the final version.
