Customers benefit from open source Open XML Translator funded by Microsoft.
Developers of the open source project to produce a translator between OpenDocument format (ODF) and Open XML document formats announced the completion of the 1.0 release of the technology. The completed Open XML Translator enables conversion of documents from one format to the other and is available for anyone to download and use at no cost. When plugged into Microsoft® Office Word, for example, the Translator provides customers with the choice to open and save documents in ODF rather than the native Open XML format. The Translator may also be plugged into competing word processing programs that use ODF as the default format to open and save documents in Open XML. Microsoft Corp. announced its support for the open source project to build a technical bridge between Open XML and ODF in July 2006 to provide interoperability between formats. Since inception, it has remained among the 30 most active projects on SourceForge.net and has been downloaded more than 50,000 times.
The Open XML Translator is one among many interoperability projects Microsoft has undertaken. Microsoft continues to work with others in the industry to deliver products that are interoperable by design and provide access to its technologies
