3. Click Browse.

Click Browse

4. Click on the Tools button and click General Options.

Note: If you only want to recommend users to open the Excel file as read-only, without protecting it, don't enter a password and check Read-only recommended.

6. Reenter the password and click on OK.

Note: this feature does not encrypt your Excel file.

7. Enter a file name and click Save.

Your workbook is read-only now.
