The latest version of Microsoft's Office suite, introduced in early 2007. The user interface in each application features an expanded toolbar called the Ribbon. The Ribbon differs from previous Microsoft applications by consolidating many functions as buttons rather than menu selections.

New Formats and Extensions
The native data formats in Office 2007 use the ECMA/Microsoft Office Open XML file structure, which is a major departure from previous file formats (see Office Open XML). However, Office 2007 documents can be saved as previous Office documents, which are compatible with files from Office 97 to Office 2003.
