Solution 1Recommended

Clear Office Document Cache and Check AutoSave

Use this solution to resolve local sync conflicts and ensure AutoSave is properly turned on for cloud collaboration.

Sometimes the local Office document cache becomes corrupted, preventing changes from uploading to SharePoint. Clearing this cache and ensuring AutoSave is active can restore normal editing and saving functions.

1
Test in Excel for the Web

Open the SharePoint document library in your browser and click the Excel file to open it in Excel for the Web. Verify if you can edit and save changes online.

2
Verify AutoSave is Enabled

If opening the file in the Excel desktop app, look at the top-left corner of the window. Ensure the 'AutoSave' toggle is turned on.

3
Clear Document Cache

In the desktop Excel app, go to File > Options > Save. Scroll down to the 'Cache Settings' section and click the 'Delete cached files' button, then click OK.

Clear Office Document Cache and Check AutoSave
AutoSave Activation: If AutoSave cannot be turned on, check if the workbook contains features not supported by co-authoring, or if someone has locked the file.

Frequently Asked Questions

Why is AutoSave disabled when I open a SharePoint Excel file?

AutoSave may be automatically disabled if the file is in an older format (like .xls), contains unsupported features like legacy shared workbook settings, or has specific security restrictions applied.

How do I force my Excel changes to save if the SharePoint sync is stuck?

You can go to File > Save As and save a copy of the workbook to your local drive. Afterward, you can manually upload this updated copy to the SharePoint library to replace the stuck file.

Does everyone need an Office 365 subscription to edit a SharePoint Excel file?

Users can edit the file in Excel for the Web for free if it is shared with 'Anyone with the link can edit' permissions, but editing via the desktop application requires a valid Microsoft 365 license.
