how to make a file read only in Excel
Q134. After several iterations, I have finalized my WorkBook - how do I make it Read-only from then on to prevent further edits?
To do it in Excel, here is the answer:
a) Click on "Info" under "File". Click on "Mark as Final" under "Protect WorkBook".
b) Click on "OK" in the pop up message indicating "This WorkBook will be marked as final and then saved." The WorkBook is now "Read-Only".
