In this article, we will explore some of the methods that can help you crack Excel password protected workbook, as well as some of the risks and limitations involved. We will also provide some tips on how to protect your Excel workbooks more securely and avoid losing your passwords.
Method 1: Use an Online Password Cracker
One of the easiest ways to crack Excel password protected workbook is to use an online password cracker service. These services use various algorithms and techniques to try to guess the password for your workbook. Some of them are free, while others charge a fee depending on the complexity of the password.
To use an online password cracker, you need to upload your workbook to their website and wait for the process to finish. If the password is found, you can download the unlocked workbook or view the password on their website. However, there are some drawbacks and risks of using this method:
It may take a long time to crack the password, especially if it is long and complex. Some online services may limit the number of attempts or the duration of the process.
It may not work for all types of password protection. Some online services may only support certain versions of Excel or certain types of encryption.
It may compromise your data security and privacy. By uploading your workbook to an online service, you are exposing your data to potential hackers, malware, or data breaches. You may also violate the terms and conditions of your Excel license or your company policy.
Therefore, before using an online password cracker, you should make sure that you trust the service provider and that you have a backup copy of your workbook. You should also check the legality and ethics of cracking a password that is not yours.
Method 2: Use a Hex Editor
Another way to crack Excel password protected workbook is to use a hex editor program. A hex editor is a tool that can edit the binary data of any file, including Excel workbooks. By using a hex editor, you can modify the code of your workbook and remove the password protection flag.
To use a hex editor, you need to download and install one on your computer, such as HxD or HexEdit. Then, you need to open your workbook with the hex editor and locate the string that indicates the password protection. You can use the search function or follow some online guides to find it. Once you find it, you need to change it to another value or delete it. Then, you need to save your workbook and open it with Excel.
However, this method also has some drawbacks and risks:
It may not work for all types of password protection. Some versions of Excel use different encryption methods or store the password in different locations.
It may damage your workbook or cause errors. Editing the binary data of a file can be risky and complicated. If you make a mistake or change something else by accident, you may corrupt your workbook or lose some data.
It may violate the terms and conditions of your Excel license or your company policy. Cracking a password that is not yours may be illegal or unethical.
Therefore, before using a hex editor, you should make sure that you have a backup copy of your workbook and that you know what you are doing. You should also check the legality and ethics of cracking a password that is not yours.
