Excel Password Encryption

Encrypt Excel with a Password

The most complete protection you can provide an Excel document is Password Encryption. It requires that someone have your password before they can open or view your workbook, and it is virtually bullet-proof. I’m not aware of any ways you can break into an encrypted Excel workbook, but I wouldn’t put it past some cyber-fiend to find a way!

That being said, two critical cautions come to mind:

  1. Don’t forget your password. There is NO password recovery feature.
  2. Don’t give your password to other people. Once you hand it out, other people can change the password on the file or remove it entirely.
