Tap "Add" to import the password-protected Excel file into the program.

Choose a mode of attack base on your situation.


Mode 1. Dictionary Attack

It is a widely used method to unlock passwords for Excel File.

It makes use of a dictionary that has millions of the most popular passwords. Thus there is a good likelihood of recovery.

You may use the built-in dictionary in this mode or import your own from the options menu.

Mode 2. Combination Attack

By adjusting the character settings and randomly mixing the characters you select, you can find your password.

For instance, you often generate a password of 6–8 characters using your name (Tom) and a few digits.

You can customize the settings as follows:

Password Length: 6-8 characters

Uppercase Letters: T

Lowercase Letters: o,m

Numbers: Select All

Just the characters you chose will be combined, and all possible combinations of these characters will be tested.

It will find your password more quickly if you use a shorter password.

Mode 3. Mask Attack

It is strongly advised that you utilize this technique if you know even a small bit about the password. It will attempt to recover the password by taking into account the characters, prefixes, suffixes, and length of the password.

If you are familiar with specific character kinds that are not in the password, this strategy will work better.

You know, for instance, that your password won't contain any symbols. You often use a password between 6 and 8 characters and believe it could incorporate your name (Mary).

You can customize the settings as follows:

Password Length: 6-8 characters

Characters not included: symbols

Characters or combinations of characters may be included: Mary

The computer will mix "Mary" with all the other characters (numbers, lowercase letters, and symbols aside from those) to determine your password. If the complete name "Mary" isn't in the password, write the letters individually.

Mode 4. Brute Force Attack

This approach should be used if you have no idea what the password to your Excel file could be.

Remember that using this approach will result in a slight delay in obtaining the file's password.

Step 3. Recover Excel Password

Click "Recover" after choosing an attack mode and customizing the settings. The password recovery process will begin. Hold off until it fixes things.

After the password is discovered, it will be shown on your screen. The password may then be used to launch MS Excel and access your file.
