The MS Office tools are known to sometimes corrupt the files they are processing. Despite the built-in recovery methods, there are still files that prove to be beyond repair. In case you have such documents, you should look for a third-party app for help. Stellar Toolkit for File Repair can take care of your Office items as well as corrupted PDF documents.

The application starts with a large panel that holds four tools, three for the Office files and one for PDF. Accessing a tool will bring up another tab that is built to handle its specific documents. Even though they might look different, in the end, all tools have the same process and steps to follow.

If you worry about data loss or other possible modifications to your files, after repairing, you shouldn't. All DOCs, PPTs, and XLS formatted documents are going to be brought to the initial state before the corruption.

Images, formatting, URLs, or any other elements are not going to be altered. This is enforced by the possibility to preview an item before outputting it. The preview feature simulates the way the repaired item is going to look like, so you won't risk any damage to it.

Besides the Office tools, the application provides an extra PDF fixer. The PDF UI is the smallest one and it's as easy-to-use as the Office ones. Just to mention it, if you are visiting the developer's site, you might get confused about the ZIP capabilities of this app. However, there is no ZIP repairing features, and that might just be a mistake or a change of heart.

Stellar Toolkit for File Repair is a neat and intuitive program that deals with corrupted Office or PDF documents. Recommended for situations where the built-in solutions failed and you just need a more powerful tool for the job.
