Open Source Word Processors

Free alternative for Office productivity tools: Apache OpenOffice - formerly known as OpenOffice.org - is an open-source office productivity software suite containing word processor, spreadsheet, presentation, graphics, formula editor, and database management applications. OpenOffice is available in many languages, works on all common computers, stores data in ODF - the international open standard format - and is able to read and write files in other formats, included the format used by the most common office suite packages. OpenOffice is also able to export files in PDF format. OpenOffice has supported extensions, in a similar manner to Mozilla Firefox, making easy to add new functionality to an existing OpenOffice installation.

LibreOffice is a free and powerful office suite, and a successor to OpenOffice. Its clean interface and feature-rich tools help you unleash your creativity and enhance your productivity. LibreOffice is Free and Open Source Software (FOSS) – development is open to new talent and new ideas, and our software is tested and used daily by a large and devoted user community. Your documents will look professional and clean, regardless of their purpose: a letter, a master thesis, a brochure, financial reports, marketing presentations, technical drawings and diagrams. LibreOffice makes your work look great while you focus on the content, thanks to its powerful styles system and structuring tools. LibreOffice is compatible with a wide range of document formats such as Microsoft® Word (.doc, .docx), Excel (.xls, .xlsx), PowerPoint (.ppt, .pptx) and Publisher. But LibreOffice goes much further with its native support for a modern and open standard (OpenDocument Format).

XML was designed from the beginning to be intolerant of errors. This decision adversely affects MS Word's corruption recovery. With one error in the document.xml subfile where all the DOCX file's text is stored, instead of a partial recovery, Word will stop and throw an error. Savvy DOCX Recovery attempts to do precise surgery on corrupt Word documents to reorder or excise bad XML tags. If this doesn't work, it uses the command line app xmllint first to attempt to repair corrupt XML subfiles of the DOCX. If this doesn't work a second attempt is made where the corrupt XML subfiles are truncated at the first error, and the correct ending tags are again added with xmllint. If all else fails, SilverCoder's DocToText is used to extract text.

Microsoft recommends methods for recovering corrupt Word files that won't open. This software provides buttons to easily invoke these as well as providing 5 independent methods for recovering and opening corrupt Microsoft Word DOC & DOCX files. Additionally the program provides links to two pieces of freeware not coded by the author, a free service (if you can wait 14 days!) and a featured commercial solution (which is an affiliate of the author's). Also it has its own native previous file version recovery tool which works in any version of Windows, Vista-Windows 10 if System Protection has been turned on in the System App of the Control Panel and a Restore Point made. Another feature is a GUI interface for finding temporary, deleted and lost versions of corrupt files. Future plans are to implement Microsoft's instructions for recovering corrupt Word files that will open. This program was formerly known as Word Recovery and more recently S2 Services Word Recovery

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.
