Mark as Final only triggers a warning; it's not encryption. Users can dismiss the notification and edit. Use sheet protection for stricter control.

Frequently Asked Questions

Can I still edit a file after marking it as final?

Does Mark as Final require a password?

No. Mark as Final doesn't use passwords or encryption. For password-protected workbooks, use File > Info > Protect Workbook > Encrypt with Password instead.

Will Mark as Final work in Excel Online?

Mark as Final is primarily an Excel desktop feature. Excel Online has limited support; the feature may not be fully available or functional in web versions.

Mark as Final flags the entire workbook as complete but doesn't restrict editing. Sheet protection locks specific cells and formulas with optional passwords for stronger control.
