The '''Office Open XML file formats''' are a set of [[file format]]s that can be used to represent electronic [[Office suite|office]] documents. There are formats for [[word processing]] documents, [[spreadsheets]] and [[presentations]] as well as specific formats for material such as mathematical formulae, graphics, bibliographies etc.

The formats were developed by [[Microsoft]] and first appeared in [[Microsoft Office 2007]]. They were standardized between December 2006 and November 2008, first by the [[Ecma International]] consortium, where they became ECMA-376, and subsequently, after a [[Standardization of Office Open XML|contentious standardization process]], by the ISO/IEC's Joint Technical Committee 1, where they became ISO/IEC 29500:2008.

=== Design approach ===

Patrick Durusau, the editor of [[OpenDocument|ODF]], has viewed the markup style of OOXML and ODF as representing two sides of a debate: the "element side" and the "attribute side". He notes that OOXML represents "the element side of this approach" and singles out the <code>KeepNext</code> element as an example:

<source lang="xml">

In August 2007, the [[Linux Foundation]] published a blog post calling upon ISO National Bodies to vote "No, with comments" during the International Standardization of OOXML. It said, "OOXML is a direct port of a single vendor's binary document formats. It avoids the re-use of relevant existing international standards (e.g. several cryptographic algorithms, VML, etc.). There are literally hundreds of technical flaws that should be addressed before standardizing OOXML including continued use of binary code tied to platform specific features, propagating bugs in MS-Office into the standard, proprietary units, references to proprietary/confidential tags, unclear [[Intellectual property|IP]] and patent rights, and much more".<ref>{{ cite web | url=http://www.linux-foundation.org/weblogs/cherry/2007/08/29/ooxml-vote-no-with-comments/ | title=OOXML&nbsp;— vote "No, with comments" | author=John Cherry | date=14 March 2008}}</ref>

The version of the standard submitted to [[ISO/IEC JTC1|JTC 1]] was 6546 pages long. The need and appropriateness of such length has been questioned.<ref name="GooglesPositiononOOXML">{{ cite web | url = http://www.odfalliance.org/resources/Google%20OOXML%20Q%20%20A.pdf | title = Google's Position on OOXML as a Proposed ISO Standard | date = February 2008-02 | publisher = [[Google]] |quote=If ISO were to give OOXML with its 6546 pages the same level of review that other standards have seen, it would take 18 years (6576 days for 6546 pages) to achieve comparable levels of review to the existing ODF standard (871 days for 867 pages) which achieves the same purpose and is thus a good comparison. Considering that OOXML has only received about 5.5% of the review that comparable standards have undergone, reports about inconsistencies, contradictions and missing information are hardly surprising}}</ref><ref>{{ cite web | url = http://www.ibm.com/developerworks/library/x-ooxmlstandard.html | title = OOXML: What's the big deal? | date = 2008-02-19 | publisher = [[IBM]]}}</ref> [[Google]] stated that "the ODF standard, which achieves the same goal, is only 867 pages"<ref name="GooglesPositiononOOXML"/>
