Microsoft Office™ 2007 shipped with a new set of file formats, namely the Microsoft Office Open XML SpreadsheetML format. This format is a semi-open standard based around a zipped XML file. Microsoft Office Open XML SpreadsheetML is mostly standardized in ECMA 376 and ISO 29500. This implementation is covered under the Open Specification Promise and therefore does not infringe upon Microsoft patents.
|Compatible Programs:||Microsoft Excel, Microsoft Office, and many other spreadsheets|
|Open / Save:||Both|
Most core features of the format are supported.
Supported by the 'MS Excel (tm)' plugin.
These are zip files containing SpreadsheetML files and binary files.
A number of other programs are able to process files in the Microsoft Excel file format.
