This Excel add-in enables users to encrypt cell contents using AES 256 bit encryption through CryptoAPI. Users may opt to secure with password or key file.

With xCELLencrypt, you have the option to encrypt with a password or through the use of a key file. This makes it ideal for individuals or organizations that share spreadsheets but need to protect certain data within the workbooks. For example, employee rosters that contain sensitive data such as social security numbers and salary information, as well as personal information like bank account numbers, user names and passwords, and security questions and answers.
If your organization regularly stores sensitive data in Microsoft Office Excel, then you simply can't go without xCELLencrypt. This software is essential for protecting important information and ensuring that it stays secure.
