Just like in the case of all other files, Excel files can also get damaged or corrupt. Usually, when this happens, the files at hand will no longer be recognizable by Microsoft Excel and errors such as "The file is not in a recognizable format" might appear.

While there's no real guarantee that you will ever be able to retrieve data from damaged Excel files, your best bet is trying out some utilities that can help you repair them, such as the appropriately-named eRepair Excel.

eRepair Excel is a lightweight and straightforward piece of software that makes it possible for you to recover data from damaged or corrupt Excel files.

This said, the first thing that needs to be mentioned is the fact that this utility supports all types of Excel formats such as XLS, XLT, XLSX, XLSM, XLTM, XLTX and XLAM.

It is also worth mentioning that the tool does not modify the retrieved data from the damaged spreadsheet and, thus, the worksheet tabs, names and the overall style and formatting options should remain untouched.

After undergoing a typical and hassle-free installation process and upon launching the app, you are greeted by its wizard-based user interface. Firstly, you are required to choose the damaged Excel file from its location. The application performs a quick scan and displays a comprehensive recovery preview.

By clicking the 'Start recovery' button, you are just one step away from finalizing the recovery/repair process. The application provides you with two options, to either save the recovered file on your computer's hard drive or to directly export it to Excel.

In conclusion, eRepair Excel is an efficient and user-friendly application that does its best to help you recover data from corrupted or damaged Excel files, without having to go through complicated procedures in order to do so.
