Fix OneDrive Stuck Processing Excel File Rename on Mac
Question details
Users are experiencing synchronization issues where OneDrive on macOS gets stuck processing changes when an older Excel file is converted to a newer format.

- Product
- Microsoft Excel and OneDrive
- Device & OS
- macOS
- Scenario
- Converting an Excel document from the older .xls format to the newer .xlsx format while keeping the same base filename in a OneDrive synced folder.
- Observed behavior
- The OneDrive synchronization engine becomes stuck on "processing changes" because it fails to properly track the temporary file creation and extension change.
Before attempting to fix the sync issue, copy the affected Excel file to a local folder outside of OneDrive (such as your Desktop) to ensure you do not lose any unsaved data.
Use a Temporary Filename and Restart OneDrive
This is the most reliable method to force OneDrive to recognize the file format change without getting stuck in a processing loop.
By saving the converted workbook with a completely different name, you bypass the tracking conflict caused by keeping the original base filename.
Quit Microsoft Excel completely and close the OneDrive application from your Mac menu bar.
Reopen the original .xls file and use 'Save As' to save it as a .xlsx file with a new temporary name (e.g., filename_temp.xlsx).
Relaunch OneDrive and wait for the application to finish syncing the newly created temporary file to the cloud.
Once synchronization is completely finished, rename the file in Finder to your desired final filename.

Pause OneDrive Syncing Before Saving
Use this workaround to prevent OneDrive from actively scanning the folder while Excel is creating temporary files during the format conversion.
Reset the OneDrive Application
If OneDrive remains stuck processing changes even after removing the problematic Excel file, you may need to reset the sync client.

Frequently Asked Questions
Why does OneDrive get stuck when changing Excel file extensions?
OneDrive can get confused when a file's format is changed (like .xls to .xlsx) but the base filename remains exactly the same. The macOS sync engine struggles to track the hidden temporary files created by Excel during this process, causing an endless processing loop.
Will I lose my Excel data if I force quit OneDrive?
Force quitting OneDrive will not delete files stored on your local hard drive. However, any recent changes that haven't yet synced to the cloud will remain strictly local until you restart OneDrive and the connection is restored.
How do I know if my Excel file has finished syncing on Mac?
Click the OneDrive cloud icon located in the upper-right corner of your Mac menu bar. If synchronization is complete, the status will read 'Up to date'. If it is still working, it will list the files currently uploading or display 'Processing changes'.
