Frequently asked questions
Can recipients still see deleted sheets?+
No. Deleted sheets are permanently removed from the file — they cannot be recovered by the recipient.
What if the hidden sheets contain lookup data my formulas depend on?+
Review the hidden sheet names first. If a sheet is used by formulas (e.g. 'Lookup_Table'), use Formula-to-Value to convert dependent formulas to static values before deleting.
