Remember that, with password protections removed, anyone with access to your Excel file can open, view, and edit it. If you've decided a password isn't necessary anymore, this likely isn't an issue.

Sending Excel files containing crucial financial and business data has risks. To add a layer of protection, you should learn to password protect an Excel file.

There are several options available to you to protect your Excel file with a password. Remember that once you protect the Excel file, you cannot open it without entering the password.

You can add or remove a password from your Excel spreadsheets through the File tab. You'll do it slightly differently on a Mac and PC.
