Coded by Ccy, author of HaHa Zip and using Delphi Zip,
Command-Line Corrupt Office 2007 Text Extractor will
often recover text from corrupt Office 2007 docx,
xlsx, and pptx format files where the respective
Office 2007 or 2010 programs cannot make the basic
salvaging of the text or data.

Office 2007 Office Open format files are zipped
collections of XML files. There are two kinds of
corruption of these types of files, zip structure
corruption and corruption of the XML files containing
the actual text or data and/or the formatting. The
unzipping module used in Office 2007 and 2010, appears
to be more finicky than InfoZip module used by Command-
Line Corrupt Office 2007 Text Extractor. Thus the
underlying XML can often be extracted as raw material
for this new program even though this is not available
to Office 2007 and 2010 programs.

In regards to the other type of corruption, XML is by
design a very unforgiving medium for file damage.
