How to Crack Excel Password with Key 6.1

If you have forgotten or lost the password to your Excel spreadsheet, you may be wondering how to crack it and access your data. There are many tools and methods available for Excel password recovery, but one of the most popular ones is Key 6.1.


Download File:

Key 6.1 is a software program that can recover passwords for Excel files (*.xls and *.xlsx) created in Microsoft Office Excel 2019, 2016, 2013, 2010, 2007, 2003, XP, 2000 and 97[^1^]. It can also remove worksheet and workbook passwords instantly. It offers three recovery methods: Brute-force attack, Mask attack and Dictionary attack. It can also use GPU acceleration to speed up the recovery process by up to 50 times[^2^].

In this article, we will show you how to use Key 6.1 to crack Excel password in a few simple steps.

Step 1: Download and install Key 6.1

You can download Key 6.1 from its official website[^2^] or from other trusted sources. The installation process is straightforward and takes only a few minutes.

Step 2: Launch Key 6.1 and select your Excel file

After installing Key 6.1, launch it and click on the "Open" button to browse and select your Excel file that you want to crack the password for. You can also drag and drop the file into the program window.

Step 3: Choose a recovery method

Depending on how much you know about your password, you can choose one of the three recovery methods offered by Key 6.1:

  • Brute-force attack: This method tries all possible combinations of characters until it finds the correct password. It is the most effective but also the most time-consuming method.

  • Mask attack: This method is useful if you remember some parts of your password, such as the length, the prefix or the suffix. You can set a mask with symbols to indicate the unknown parts of your password, and Key 6.1 will try only those combinations that match the mask.

  • Dictionary attack: This method is based on a predefined dictionary of common words or phrases that people use as passwords. You can use the default dictionary provided by Key 6.1 or create your own one.

You can also adjust some settings for each method, such as the character set, the password length range, or the GPU acceleration option.

Step 4: Start the recovery process

After choosing a recovery method and setting the options, click on the "Start" button to begin the recovery process. Key 6.1 will display the progress and estimated time on the screen. You can pause or stop the process at any time.

Step 5: Recover your password

When Key 6.1 finds your password, it will show it on the screen and also save it in a text file. You can then copy and paste it to open your Excel file.


Key 6.1 is a powerful and easy-to-use tool for Excel password recovery. It can crack passwords for various versions of Excel files with different recovery methods and options. It can also remove worksheet and workbook passwords instantly. However, it is not a free tool and it may not work for some newer versions of Excel files[^3^]. If you are looking for an alternative solution, you can try some online services or other software programs that offer similar features. e0e6b7cb5c
