Corrupt Office 2007 Extractor will extract the text/data from corrupt docx, xlsx, and pptx files where the respective MS Office files error out and refuse to open. In advanced mode the program can fix the zip structure of these new "Office Open XML" format files, a step which I now recommend despite our dissuasive blurb which comes up when you start that function.
Advanced mode also allows recovering images and if you are familiar with XML, includes is a basic XML editor for editing corrupt XML which might be causing the docx, xlsx or pptx corruption.
Additionally I recommend using trying newer program, Savvy Office Recovery, which is available on Sourceforge. It will often recover formatting as well as text. Also of possible interest are S2 Recovery Tools for Excel and S2 Recovery Tools for Word on Sourceforge. The last two use different algorithms than the present program.
Previously known as Corrupt Office Extractor and Corrupt Office 2007 - 2013 Text Extractor.
