Kutools for Excel is a popular third-party add-in that extends Excel's functionality with over 300 tools. When it comes to "passwords," Kutools addresses two distinct areas: unprotecting worksheets/workbooks (recovering or removing forgotten passwords) and managing file open passwords.
Important Security & Legal Note
- Legitimate use: Removing protection from your own files where you've forgotten the password is legal and supported.
- Illegitimate use: Do not use Kutools to bypass protection on files you do not own or do not have permission to modify. This may violate copyright, employment agreements, or laws like the Computer Fraud and Abuse Act (CFAA) in the US.
- Excel's security is not "broken": The fact that Kutools can remove sheet protection without a password is because sheet protection is a user interface lock, not strong encryption. It prevents accidental edits, not determined access.
