Explanation
Sometimes, when editing .docx files in LibreOffice or OpenOffice,
the file becomes corrupted. Often, the error will exhibit as a SAXException.
LibreOffice will offer to repair the file, but the repaired file will sometimes be severely truncated.
This site attempts a fix with a different approach. We can't guarantee that it will work for your file, but you have nothing to lose.
Your file is sent to the server, where it attempts a correction in-memory and returns a (hopefully) fixed version. We do not store your file on our server at all.
