Question details
The user wants to prevent accidental edits in shared Excel workbooks by enabling View-Only mode, but the viewing option is sometimes unavailable.

- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Viewing shared workbooks in a browser without accidentally modifying data.
- Observed behavior
- Shared workbooks are being accidentally edited because the View-Only option is disabled or unavailable, leading to unintended data modifications.
Before proceeding, check your current permission level for the shared workbook and ensure you have saved a backup copy in case you need to restore accidentally deleted content.
Switch to Viewing Mode or Protect the Worksheet
Use the built-in Viewing mode or apply worksheet protection to prevent accidental cell modifications.
If you only need to read the data, switching to a dedicated reading mode ensures you don't overwrite cells by mistake. When that fails, applying a protection password is the safest fallback.
Locate the mode switcher in the top ribbon of your browser (usually displaying 'Editing' or 'Viewing'). Click it and select 'Viewing' to switch to read-only mode.
If the Viewing option is disabled, navigate to the 'Review' tab on the ribbon and click 'Protect Sheet'.
Enter a password if prompted, uncheck the options that allow users to select or format cells, and click 'OK' to lock the document.

Use Version History and Show Changes to Recover Data
Identify automated actions or recover accidentally deleted content using Excel's version tracking features.

Frequently Asked Questions
Why is the Viewing mode option disabled in my shared Excel file?
The Viewing mode might be disabled due to specific sharing settings applied by the owner. If you were granted 'Edit' access, some platforms lock you into Editing mode by default. You can request the owner to reshare the file with strictly 'View only' permissions.
Can I undo a change made by someone else in a shared workbook?
No, the standard Undo function typically only reverses your own recent actions. To reverse another user's edits, you must use the 'Show Changes' feature to identify the edit, or restore a previous version from the Version History pane.
Could automated actions cause accidental deletions in a shared file?
Yes, automated actions like macros or background scripts can modify or delete cell content without direct user interaction. If unexpected changes occur while you are the only one in the file, check if any macros or add-ins are running.
