As a note of full disclosure, I sponsored some of the recent development of this application, especially regarding corrupt MS Office 2007 extracting capabilities. That being said, this is a fantastic command line text/data extractor from MS Office files. I do have experience with it extracting text from corrupt docx and pptx files where Word and PowerPoint 2007 themselves fail. Additionally I have experience with it extracting data from corrupt xlsx files. It may not be as effective in recovering text from corrupt doc Word 97-2003 files, Open Office or RTF ones, I only have limited experiences with these. They have yet to include features allowing recovering of data from Excel 97-2003 or text from PowerPoint 97 - 2003 corrupt or not. This software is a very effective command line extractor of text from doc, docx, pptx, odt, ods, odp and rtf non-corrupt files as well as data from xlsx files. Data from xlsx files are returned in tab format text files as opposed to the perhaps more common csv format. This app is very well suited as an easy building block or back end for powerful corrupt Office 2007 extracting GUI or web service and MS Office, Open Office and RTF non-corrupt converters. Again it is possible the program will work corrupt doc, odt, ods, odp and rtf files but I have limited experience with these.
