Watch How to Protect a Range
Protected Ranges allows you to select a range of cells and choose which collaborators have permission to edit those cells, and which collaborators should only be able to view those cells.
Protect a named range
When creating a new range, you’ll see the option to protect your range before saving it:
- After defining and naming the range, check the Protect checkbox, and click Done. This will open a dialog box that lists your document collaborators and their access settings.
- To change a collaborator’s access to the range, click on the drop-down menu to the right of their name and choose to grant them Comment or Edit access.
- Click Done.
To protect a range you had previously named and defined, follow these steps:
- Select that range in the Named and protected ranges panel.
- Click the Edit button.
- Click Add permissions (or Modify permissions if you are making changes to range protection settings). From here, follow steps 2-3 above.
Collaborators who try to edit a cell in a protected range they don’t have edit access to will receive an error message. When opening a spreadsheet with protected ranges, individuals will see ranges they don’t have edit access to displayed with a checkered background. If the background pattern makes it difficult to read spreadsheet content, you can hide protected ranges by pointing your mouse to the View menu and unchecking Protected Ranges.
