Hiding a tab reduces visual clutter. It does not create a separate permission boundary for the data in that tab.
Hide or restore the tab
Open the tab’s menu and choose Hide sheet. Google requires at least two sheets for that option to appear. Use the View menu’s hidden-sheet entry to show the tab again.
Before hiding a calculation tab, give it a clear name and keep its purpose documented. Other formulas may continue to depend on it even when it is not visible in the tab bar.
Understand who can reach the content
Spreadsheet editors can unhide sheets. Google also warns that viewers can still access hidden-sheet content, including through a permitted copy that can be unhidden.
Do not store salaries, credentials, private customer records, or another restricted dataset in a hidden tab of a broadly shared file. Separate files with appropriate access are needed when audiences differ.
Review distribution and dependencies
Check exported files and any publishing configuration according to their actual scope. Hidden presentation state is not a reliable assurance that every format or route excludes the underlying content.
If an old tab is no longer needed, deletion is a separate decision requiring dependency and recovery checks. Hiding can be useful while preserving calculations, but it should not obscure undocumented business logic from maintainers. Verify that visible reports still calculate correctly and that team members know how to locate supporting data. A cleaner tab bar improves navigation; it does not reduce the sensitivity of the file or revoke access that was already granted to its readers.
