When a file is shared by many people
If you want to prevent someone from accidentally deleting a sheet or renaming it in a file the whole team views, Protect Workbook keeps the structure safe.
Removing duplicates is worth checking too
Once a shared file is protected against structural changes, it is also worth periodically checking it for duplicate entries to keep the data itself clean and reliable.
Frequently Asked Questions
Does protecting the workbook also prevent editing cell contents?
No β Protect Workbook blocks structural changes like adding, deleting, or reordering sheets; to prevent editing cell contents, you need to set up "Protect Sheet" separately.
If I forget the password, can protection be removed?
Generally no β there is no built-in recovery method by default, so be sure to store any password you set somewhere safe.
