A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data
In Excel for Mac, Protection is not a ribbon tab. It appears as a tab inside the Format Cells dialog box.
To find it on a Mac:
- Select the cell or range.
- Press Command + 1 or go to Format > Cells.
- In the dialog box, open the Protection tab.
That tab contains options such as:
- Locked for locking cells
- Hidden for hiding formulas
Important: setting Locked alone does not protect the cells until the sheet is protected. To enforce it, go to Review > Protect Sheet.
If the sheet is already protected and cells cannot be changed, use Review > Unprotect Sheet first.
