Office Open XML (also informally known as OOXML or Microsoft Open XML (MOX)) is a zipped, XML-based file format developed by Microsoft for representing spreadsheets, charts, presentations and word processing documents. The format was initially standardized by Ecma, and by the ISO and IEC in later versions.
Binary DOC files often contain more text formatting information (as well as scripts and undo information) than some other document file formats like Rich Text Format and Hypertext Markup Language, but are usually less widely compatible. In Microsoft Word 2007 and later, the binary file format was replaced as the default format by the Office Open XML format, though Microsoft Word can still produce DOC files.
