Part 1: How to Recover Opening Password for Excel File

These are the steps to recover passwords for which Excel prompts you when you open an Excel document.

Step 1Select Unlocking Mode

Launch Passper for Excel. Select the "Recover Passwords" mode.

Step 2Add the Encrypted Excel File and Select an Attack Type

Click "Add" to import the password-protected Excel file into the program. Then choose a mode of attack according to your situation.

Note: Here is a detailed description of the 4 modes of attack. If you are still not sure which mode to choose after reading it, you can send us an e-mail to

1. Dictionary Attack

It is a widely used method to unlock passwords for many types of files. It uses a dictionary which contains millions of the most commonly used passwords. Thus the chance of recovery is high. By using this mode you can take advantage of the built-in dictionary or import your own from the settings menu.

2. Combination Attack

Find your password by customizing the character settings and randomly combining the characters you choose.

For example, you usually use your name (Tom) and some numbers to create a password of 6-8 characters. You can customize the settings as follows:

Password Length: 6-8 characters
Uppercase Letters: T
Lowercase Letters: o,m
Numbers: Select All

The program will combine only the characters you choose and try all the combinations of these characters. The fewer characters you choose, the faster it will find your password.

3. Mask Attack

If you have a little clue about the password, you are highly recommended to use this attack. It will consider the characters, prefixes, suffixes, and length of the password and try to recover the password. This method will be better if you know certain character types not included in the password.

For example, you are sure that your password won't have symbols. You think that your password may contain your name (Mary) and you usually set a password of 6-8 characters. 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 program will combine all the other characters (uppercase letters, lowercase letters, numbers except symbols) with "Mary" to find your password. If your name "Mary" doesn't appear in the password in its entirety, write the letters separately.

4. Brute Force Attack

If you have no clue about what the password of your Excel file could be, this is the method you should choose. Bear in mind that this method will take a little longer to find out the password for your file.

Step 3Recover Excel Password

Once you have selected a mode of attack and customized the settings, click "Recover". The program will start recovering the password. Wait while it works on it. The password will be displayed on your screen when it is found. Then you can use the password to open your file with MS Excel.
