Previously known as Damaged DOCX2TXT, this GUI program will extract text from damaged/corrupted Word 2007 - 2013 DOCX format documents.
DOCX files are actually zipped collections of mostly XML files. The main text in docx files is found in document.xml file in the collection. Corrupt DOCX Salvager uses 7Zip, an unzipper that sometimes unzips partially corrupt document.xml files despite reporting an error.
XML as a format is unforgiving of data corruption but Corrupt DOCX Salvager uses a Perl routine used to extract the text from the document.xml file which doesn't care about well-formed XML, a recovery stumbling block for Microsoft Word.
Recent changes include the pretreatment of docx files with InfoZip's zip.exe -FF repair command, improving success rates. Also added are links to other solutions.
If you are unsatisfied with the results, try my other corrupt Word recovery capable programs here on Sourceforge, S2 Recovery Tools for Word and Savvy DOCX Recovery.
