Device & OS
Android
Scenario
Attempting to edit an Excel spreadsheet on a mobile device using the Microsoft Excel app.
Observed behavior

Before you start

Ensure your Android device has a stable internet connection and that you know the exact Microsoft account credentials associated with your active subscription.

Solution 1Recommended

Verify Account and Microsoft 365 Subscription Sync

Ensuring your Android app uses the same account as your PC and has an active subscription is the most common fix for read-only restrictions.

Microsoft Excel requires an active Microsoft 365 subscription for full editing capabilities on many mobile devices. If your app is not recognizing your account or subscription, it will default to a read-only view.

1
Check subscription status

Open a web browser and go to account.microsoft.com. Navigate to 'Services & subscriptions' to confirm your Microsoft 365 plan is active and valid.

2
Verify Android sign-in

Open the Excel app on your Android phone, tap your profile icon at the top left, and verify that the email address exactly matches the one you use on your PC.

3
Re-sign into the app

If the account is incorrect or shows an unrecognized error, tap 'Sign out' within the account settings. Restart the Excel app, tap 'Sign in', and enter the correct Microsoft credentials.

Test Other Apps: Try opening the Microsoft Word or PowerPoint apps on your Android phone. If you can edit documents there, the issue might be specific to the Excel app installation rather than your account.

Frequently Asked Questions

Why are my Excel files suddenly read-only on Android?

This typically happens if your Microsoft 365 subscription has expired, the app is not signed into the correct Microsoft account, the file was sent as an email attachment and hasn't been saved locally, or the file itself is locked by another user.

Do I need a paid subscription to edit Excel files on Android?

Microsoft allows basic editing for free on devices with screen sizes under 10.1 inches, but requires a qualifying Microsoft 365 subscription for premium features or larger devices. If you face subscription barriers, a free alternative like WPS Office allows robust editing without a subscription.

How do I fix the 'unrecognized account' error in Excel for Android?

Navigate to your Android Settings > Apps > Excel, and clear the app cache and data. Then, force stop the app, reopen it, and carefully sign back in using the exact email address tied to your active Microsoft account.

How can I tell if the read-only issue is specific to a single file?

Try creating a brand new spreadsheet within the Excel app. If you are able to type and save the new document, your account permissions are fine, and the issue lies with the specific file (e.g., it is marked as 'Final' or contains unsupported macros).
