Office Open XML file formats

<p>The Office Open XML file formats are a set of <a href="/facts/File_format/qrXbwJaH">file formats</a> that can be used to represent electronic <a href="/facts/Office_suite/WcKtjN6j">office</a> documents. There are formats for <a href="/facts/Word_processing/qAR7lagF">word processing</a> documents, <a href="/facts/Spreadsheets/0cvc1GeB">spreadsheets</a> and <a href="/facts/Presentations/InRKd0W2">presentations</a> as well as specific formats for material such as mathematical formulas, graphics, bibliographies etc.
</p><p>The formats were developed by <a href="/facts/Microsoft/nGIDDXdx">Microsoft</a> and first appeared in <a href="/facts/Microsoft_Office_2007/6qxbuGxr">Microsoft Office 2007</a>. They were standardized between December 2006 and November 2008, first by the <a href="/facts/Ecma_International/HCbnIU6n">Ecma International</a> consortium, where they became ECMA-376, and subsequently, after a <a href="/facts/Standardization_of_Office_Open_XML/eUypRd76">contentious standardization process</a>, by the ISO/IEC's Joint Technical Committee 1, where they became ISO/IEC 29500:2008.
