Solution 1Recommended

Use Excel for the Web in a Mobile Browser

Since the Excel mobile app has limitations with worksheet protection, bypassing the app and using the web version allows you to edit the file on your mobile device.

This limitation is specific to the Excel mobile application itself. Microsoft's mobile app currently restricts editing on protected worksheets, keeping them in a read-only state. You can bypass this by accessing the web version.

1
Open your mobile browser

Launch Chrome, Safari, or your preferred web browser on your mobile device.

2
Navigate to Microsoft Office Web

Go to office.com and log in with the Microsoft account associated with your Excel file.

3
Open the workbook

Locate your Excel file in your OneDrive or SharePoint files and tap to open it in Excel for the Web.

4
Enter the password

When prompted, enter the worksheet protection password to unlock the specific areas and begin editing.

Frequently Asked Questions

Why does the Excel mobile app show my protected sheet as view-only?

The Microsoft Excel mobile app has known feature limitations regarding protected worksheets. Even if you have the correct password and can edit the file on a PC, the mobile app restricts editing in certain protected ranges to maintain data integrity, leaving the worksheet in a read-only state.

How can I permanently make my worksheet editable on the Excel mobile app?

To edit the file seamlessly in the mobile app, you must remove the worksheet protection entirely using the Excel desktop application. Go to the Review tab, select 'Unprotect Sheet', enter your password, and save the file.

Does this editing limitation apply to workbooks that require a password to open?

No. This specific view-only limitation typically applies to worksheet-level protection (where specific cells or ranges are locked to prevent modification). If the entire workbook is simply encrypted with a password to open, the mobile app can usually open and edit it once the master password is provided.
