Use the Desktop Version of Excel

Because the Android app does not support sheet protection controls, you must use a desktop computer to modify the protection status of your worksheets.

Worksheet protection requires advanced settings that are currently omitted from the mobile application to keep the interface lightweight. You can bypass this limitation by syncing your file to a cloud service and opening it on a desktop.

Save to the cloud

Save your current Excel workbook to a cloud storage service like OneDrive, Google Drive, or Dropbox from your Android device.

2
Open on a desktop computer

Launch Microsoft Excel on your Windows or Mac computer and open the synchronized file.

3
Navigate to the Review tab

Click on the 'Review' tab located in the top ribbon menu of the Excel interface.

4
Manage sheet protection

Click on 'Protect Sheet' or 'Unprotect Sheet'. Enter the password if prompted, apply your changes, and save the document so it updates on your mobile device.

Cloud Sync Delay: Make sure your changes are fully synced to the cloud on your desktop before attempting to view the updated file on your Android device.
