Hi Alan,
Welcome to the Microsoft Q&A forum.
To turn off Read-only mode for Excel files, you can try the following steps:
- Disable the Read-only attribute for the file
Right-click the Excel file > select Properties > uncheck Read-only > select Apply > OK.
- Disable the option to always open the file in Read-only mode in Excel
- Open the Excel file > select File > Info > Protect Workbook.
- Uncheck Always Open Read-Only.
- If the file was shared with you by someone else
If the file was shared with you and you only have read-only access, you will need to contact the file owner and ask them to check your permissions and grant you Edit access.
I hope this information is helpful.
If you have any questions or need further assistance, please feel free to share them in the comments on this post so I can continue to support you.
