Programs to unprotect Excel files
As I mentioned at the beginning of the guide, if you need to unprotect an Excel file whose password you can’t remember, you can use some programs purposely used for this purpose, thanks to which it is possible to identify the access key to a spreadsheet even if it has been lost.
The software in question works in two different ways: through the attack brute force and by dictionary attack.
In the first case, the program used tries to identify the set password by trying all possible combinations of letters, special characters and numbers, which is particularly effective for hotkeys. While in the second case, lists of passwords that include grades. in special dictionaries, a preferred solution in the case of weak passwords.
However, the success of these tools, keep in mind, essentially depends on the length and complexity of the password set, so I cannot give you absolute certainty that using them you can get the desired result, but, as they say, test doesn’t hurt
