If you're seeing the "Read-Only" status in Excel, it means that the workbook you're trying to open is marked as read-only. This can happen for a number of reasons:

• The workbook is stored on a read-only file system, such as a CD-ROM.
• The workbook has been opened as read-only by another user.
• The workbook has been marked as final.

If you're the owner of the workbook and you want to edit it, you'll need to remove the read-only status. To do this, open the workbook in Excel and click on "File" > "Save As". In the "Save As" dialog box, click on the "Tools" button and then select "General Options". In the General Options dialog box, clear the "Read-only recommended" check box and click "OK". Now when you save the workbook, the read-only status will be removed.
