How to Fix Excel and OneDrive Files Freezing or Failing to Open
Question details
The user is experiencing performance issues where Excel freezes on Windows and OneDrive files close unexpectedly on mobile devices.

- Product
- Microsoft Excel, Microsoft OneDrive
- Device & OS
- Windows, Android
- Scenario
- Attempting to open, edit, or synchronize recent Excel files stored on OneDrive across multiple devices.
- Observed behavior
- Excel becomes completely unresponsive on Windows, while files on Android tablets close within seconds of opening. Newer files fail to load or lack recent changes, even after clearing caches and reinstalling the apps.
Verify that your device has an active, stable internet connection and note the exact folder path of the problematic Excel files in your local OneDrive directory.
Run Excel in Safe Mode and Disable Add-ins
Starting Excel in Safe Mode helps identify if third-party add-ins are causing the application to freeze or crash upon opening.
COM add-ins can sometimes conflict with Excel's core processes, especially when syncing data with cloud services like OneDrive. Safe Mode bypasses these add-ins.
Press the Windows key + R on your keyboard to open the Run dialog box.
Type 'excel /safe' into the text box and press Enter to launch Microsoft Excel.
Click on 'File' in the top ribbon, select 'Options' at the bottom left, and then click on 'Add-ins'.
At the bottom of the window next to 'Manage', select 'COM Add-ins' from the dropdown menu and click 'Go'. Uncheck all listed add-ins and click 'OK', then restart Excel normally.

Check OneDrive Synchronization and Open Files Locally
Incomplete synchronization can cause newer files to fail to open or appear without recent changes.
Update Office and Device Operating Systems
Outdated software versions can lead to compatibility bugs between Excel and OneDrive across different platforms.
Switch to WPS Office for a Stable and Smooth Experience
If Excel continues to freeze or struggle with cloud synchronization, WPS Office provides a lightweight, highly compatible, and free alternative. It avoids heavy background sync conflicts and works flawlessly across Windows, Android, and macOS.

Frequently Asked Questions
Why does Excel freeze when opening files from OneDrive but not local files?
This usually occurs due to network latency, incomplete synchronization, or background sync conflicts between the Office Upload Center and OneDrive. Opening the file from your local synced folder after OneDrive has finished updating can bypass this issue.
Will reinstalling OneDrive fix the Excel freezing issue?
Reinstalling can resolve the issue if the OneDrive cache is corrupted. However, if the freezing persists after a reinstall, the problem is more likely related to problematic Excel add-ins or an outdated Windows operating system.
How do I recover an Excel file that closed before saving?
Open Excel, go to File > Info > Manage Workbook, and click 'Recover Unsaved Workbooks' from the dropdown menu to check for temporary autosaved backups of your spreadsheet.
Why do my Excel files crash immediately on my Android tablet?
Mobile app crashes are often caused by inadequate device memory, a corrupted application cache, or an outdated Android version. You can fix this by clearing the cache via Settings > Apps > Excel > Storage > Clear Cache.
