Question details
Users are unable to edit specific cells in Excel for the web because cells that were unlocked in the desktop app incorrectly appear as locked and protected online.

- Product
- Microsoft Excel for the web
- Device & OS
- not provided
- Scenario
- Attempting to edit a partially protected workbook in Excel online.
- Observed behavior
- Cells that are explicitly unlocked in the desktop version of Excel are treated as locked and cannot be edited when the file is opened in Excel for the web.
Verify if the issue persists across different web browsers or after clearing your browser cache. Also, ensure you have the necessary editing permissions for the shared workbook.
Open the File in the Desktop Application
Bypass the web-based glitch by editing the workbook directly in the desktop version of Excel, where cell permissions are handled correctly.
Since the bug is isolated to Excel for the web, the quickest workaround is to utilize the desktop application. Desktop software accurately reads the protection metadata, allowing you to edit the explicitly unlocked cells without issue.
While viewing the file in Excel for the web, click the 'Editing' dropdown menu on the ribbon and select 'Open in Desktop App'.
Wait for Excel to launch locally. Once opened, navigate to the unlocked cells and proceed with your data entry or edits.
Save your document. The changes will automatically sync back to the cloud.
Submit a Support Request via Microsoft 365 Admin Center
If the bug persists on your tenant, report it directly to Microsoft for a backend fix.
