How to Fix Excel Desktop and Online Synchronization Problems
Question details
Users are experiencing issues where changes made in the Excel desktop application do not synchronize with Excel Online.
- Product
- Microsoft Excel
- Device & OS
- Mac
- Scenario
- Editing an Excel workbook shared via OneDrive or SharePoint using both the desktop app and the online version simultaneously or interchangeably.
- Observed behavior
- Changes fail to sync between the desktop app and the online version, often due to account conflicts, the workbook operating offline, or incorrect file storage locations.
Ensure your internet connection is stable and verify that your Excel file is saved in an active OneDrive or SharePoint folder before attempting to fix synchronization errors.
Re-Sign Into Your Correct Office Account on Mac
Signing out and back in can resolve account conflicts that block synchronization between Excel desktop and online versions.
If you are logged into the wrong account or facing a credential error on your Mac, Excel may block the synchronization of your shared files. Re-establishing the connection with your designated work or school license usually resolves this.
Open the Excel application on your Mac. Click on the 'Excel' menu at the top left of the screen and select 'Sign Out'.
Close all applications and restart your computer to clear temporary session data.
Relaunch Excel and sign in using the exact account that owns the Microsoft 365 work or school license associated with the shared file.
Run the Microsoft Office License Removal Tool
Use this method if persistent account errors continue to block syncing and signing out is not enough.
Verify OneDrive or SharePoint File Location
Excel sync requires the file to be properly stored in a supported cloud location with the necessary edit permissions.
Try WPS Office for Seamless Cloud Syncing
Avoid complex license and synchronization errors with WPS Office. It provides a lightweight, highly compatible alternative to Microsoft Excel with built-in cloud storage for effortless cross-device synchronization.
- 1. Download and Install WPS Office: Visit the official WPS website and download the free application for your Mac or PC.
- 2. Open Your Excel File: Launch WPS Spreadsheets and open your existing .xlsx file without losing any data or formatting.
- 3. Save to WPS Cloud: Click 'Save As' and select WPS Cloud to ensure your changes are safely synchronized and accessible across all your devices.
Frequently Asked Questions
Why does Excel say my file is offline when I have an active internet connection?
This can happen if your local OneDrive client is paused, not running in the background, or experiencing an account credential conflict. Restarting the OneDrive app or signing back into Excel usually restores the connection.
Will simply reinstalling Microsoft Office fix the synchronization issue?
Not always. Reinstalling Office on a Mac does not automatically remove background account activations or Outlook profiles. You must use the Office License Removal Tool to properly clear old credentials.
How do I know if my Excel file is stored in a supported cloud location?
Look at the title bar in your Excel desktop app. If the AutoSave toggle is enabled and the file path indicates OneDrive or SharePoint, it is properly stored for online syncing.
