How to Fix Excel Files Not Opening in Microsoft 365 Android App
Question details
Users are unable to open certain Excel files stored in OneDrive using the Microsoft 365 Android application, receiving an error that a problem was found with the file.
- Product
- Microsoft 365 App, Excel, OneDrive
- Device & OS
- Android
- Scenario
- Accessing and opening OneDrive-stored Excel workbooks from a mobile device using the Microsoft 365 Android app.
- Observed behavior
- The Excel file opens successfully in a web browser but intermittently fails to open in the Android app, throwing an error message.
Verify that your Android device has a stable internet connection and ensure that you can log into your Microsoft account through a standard mobile web browser.
Clear App Cache and Update Microsoft Apps
Outdated application versions or corrupted local cache data frequently cause OneDrive synchronization and file loading failures on Android devices.
Local cache issues can prevent the Microsoft 365 app from properly reading files hosted on OneDrive. Clearing this data forces the app to fetch a fresh version of the file.
Open the Google Play Store on your Android device, search for 'Microsoft 365' and 'OneDrive', and tap 'Update' to ensure both apps are on the latest versions.
Navigate to your Android device 'Settings', tap on 'Apps' or 'App Management', and select the 'Microsoft 365' app from the list.
Tap on 'Storage & cache', then select 'Clear cache' to remove temporary local files that might be causing the error.
Return to the apps list, select 'OneDrive', and clear its cache as well. Restart your device and try opening the Excel file again.
Re-authenticate and Test a Local Copy
Refreshing your account login token or downloading the file directly to your device storage can bypass cloud integration glitches.
Use WPS Office for Android to Open Excel Files Reliably
If the Microsoft 365 Android app continues to struggle with your OneDrive files, switch to WPS Office. It is a lightweight, highly compatible alternative that opens complex Excel spreadsheets smoothly on mobile devices without cache errors.
- 1. Install WPS Office: Download and install WPS Office for free from the Google Play Store on your Android device.
- 2. Connect Cloud Storage: Open WPS Office, navigate to the 'Cloud' tab, select 'Add Cloud Storage', and log in with your OneDrive account.
- 3. Open Your File: Browse your OneDrive folders directly within WPS Office and tap your Excel file to open and edit it smoothly.
Frequently Asked Questions
Why do my Excel files open perfectly in the web browser but fail in the Android app?
The web browser accesses the file directly from Microsoft's cloud servers, bypassing your device's local environment. The Android app relies on local cache, synchronization tokens, and device memory, which can become corrupted or fall out of sync with OneDrive.
What should I do if clearing the app cache does not resolve the error?
If clearing the cache fails, completely uninstall both the Microsoft 365 and OneDrive apps, restart your phone, and reinstall them from the Google Play Store. You should also try opening a locally downloaded copy of the file to determine if the file itself is corrupted.
Could the size of my Excel file be causing it to crash the mobile app?
Yes. Mobile devices have stricter memory and processing limits compared to desktop computers. Large Excel workbooks, particularly those with complex formulas, macros, or heavy graphics, may time out or fail to render in the Android app even if they work fine on a PC.
