Truthfully, I can't be trusted with anything nice—and this extends to beautifully formatted, formula-filled Google Sheets spreadsheets. I get all click-happy, and the next thing I know, I'm staring at empty cells where there were once data-filled cells. 

Sure, I could hit Undo, but that's helpful only if I know what errors I need to undo. Or the person sharing their spreadsheet with me could limit my permissions to view or comment only. But that's not practical if we need to collaborate on the file. 

Google rightfully predicted there were more click-happy humans like me, which is why they added the ability for users to protect certain cell ranges and sheets from being tampered with. 

Here's how to lock cells and sheets in Google Sheets.

How to lock cells in Google Sheets

1. Open a Google Sheets spreadsheet. 

2. Highlight the cell or cell range you want to protect. 

3. Click Data > Protect sheets and ranges. Alternatively, right-click your selection, and then click View more cell actions > Protect cell range. 

   

4. In the Protected sheets & ranges panel that appears, click Set permissions. 

   

5. Modify the Range editing permissions in one of the following ways: 

   • Show a warning when editing this range. Other users can still edit the protected range, but they'll get a warning first. This is a good option for dealing with click-happy collaborators.  

     

   • Restrict who can edit this range. You can limit this to Only you. Or you can apply custom settings, giving specific people permission to edit the range. 

     

6. Optionally, in the Protected sheets & ranges panel, enter a description for the locked cells. This is especially practical if you're managing multiple locked sheets and cell ranges. 

7. Click Done. 

Now, when someone who doesn't have permission to edit a cell range tries to modify it, they'll get a popup notifying them that the cell is protected and to contact the spreadsheet owner to remove the protection, if needed.

3. Select the sheet you want to lock. 

4. Optionally, check Except certain cells to make certain cells within the locked sheet editable. 

   

5. Click Set permissions.
