Office 2007 and above versions all use AES encryption, and there is no other way to unlock files. You can only guess the password by trying it with a password. The number of passwords is an astronomical number, and it is not possible to try all of them. For example, an 8-digit lowercase letter and number can reach a password of 28000 billion. Under normal circumstances, many passwords used exceed 8 digits in length. It is impossible to run all the passwords with violence.
If you can't recall the password you used, you can use our password cracking service. Charge only after successful decryption
