Statistically we tend to forget our passwords once in every six months. This means if you have a password protected MS Excel document then sooner or later your password will be lost.

In such cases people usually have two solutions. First solution involves downloading expensive software tools which could be used on your PC to crack your Excel password protection. The second solution is to use our online service which does not require any software downloads. You pay only if we can successfully restore your MS Excel password or remove protection of your Excel document.

Want to learn more? Here is some additional information.
Historically MS Excel was equipped with weak password protection. If you are using Excel versions prior to 2003 it is easy to break a sealed document and read the locked spreadsheet. These days Microsoft Excel supports several types of protection, including password to open, which forbids unauthorized access and protection from modification.

Excel 97 and 2000 utlize another algorithm which is computationally harder to break. The chances of restoring an Excel spreadsheet sealed in Excel 97 or 2000 versions are higher if the password is short. However, we have developed effecient code which allows us to recover any password protected document within minutes.

In later versions of Microsoft Excel the password encrypted files could be protected with AES encryption method. In such case your only choice would be running a brute search with all possible combinations of passwords. We offer optimized variants of these attacks ensuring that used dictionary closely corresponds to your possible passphrase. We utilize our data center to perform distributed attack which significantly improve your chances of getting data back in readable format.

Please check the following table which lists different algorithms used in Microsoft Excel.

What our users say

My wife has forgotten the password for our home finance tracking spreadsheet. When I opened the file in Excel I got: "The password you supplied is not correct. Verify that the CAPS LOCK key is off and be sure to use the correct capitalization." It would be fair to say that these guys did a great job, their app really works.
