NCrypt XL is a tool to encrypt every cell inside a MS Excel spreadsheet. It uses standard algorithms such as AES and DES. The encryption is text based, and any format is retained. Encryption and decryption is done by inserting a proper password or passphrase. Every single worksheet may be encrypted entirely or by selecting one or more of its columns. NCrypt XL is a standalone solution, not an Excel macro. It is compatible with MS Excel version 2003 and above.
