The format was initially standardized by Ecma ( as ECMA - 376 ) , and by the ISO and IEC ( as ISO / IEC 29500 ) in later versions . Starting with Microsoft Office 2007 , the Office Open XML file formats have become the default target file format of Microsoft Office . Microsoft Office 2010 provides read support for ECMA - 376 , read / write support for ISO / IEC 29500 Transitional , and read support for ISO / IEC 29500 Strict . Microsoft Office 2013 and Microsoft Office 2016 additionally support both reading and writing of ISO / IEC 29500 Strict .

In 2002 , a new file format for Microsoft Word followed . The Excel and Word formats -- known as the Microsoft Office XML formats -- were later incorporated into the 2003 release of Microsoft Office . Microsoft announced in November 2005 that it would co-sponsor standardization of the new version of their XML - based formats through Ecma International as `` Office Open XML '' . The presentation was made to Ecma by Microsoft 's Jean Paoli and Isabelle Valet - Harper . Standardization process ( edit ) Main article : Standardization of Office Open XML Microsoft submitted initial material to Ecma International Technical Committee TC45 , where it was standardized to become ECMA - 376 , approved in December 2006 . This standard was then fast - tracked in the Joint Technical Committee 1 of ISO and IEC . After initially failing to pass , an amended version of the format received the necessary votes for approval as an ISO / IEC Standard as the result of a JTC 1 fast - tracking standardization process that concluded in April 2008 . The resulting four - part International Standard ( designated ISO / IEC 29500 : 2008 ) was published in November 2008 and can be downloaded from the ITTF . A technically equivalent set of texts is published by Ecma as ECMA - 376 Office Open XML File Formats -- 2nd edition ( December 2008 ) ; they can be downloaded from their web site . The ISO standardization of Office Open XML was controversial and embittered , with much discussion both about the specification and about the standardization process . According to InfoWorld : OOXML was opposed by many on grounds it was unneeded , as software makers could use OpenDocument Format ( ODF ) , a less complicated office software format that was already an international standard . -- InfoWorld The same InfoWorld article reported that IBM ( which supports the ODF format ) threatened to leave standards bodies that it said allow dominant corporations like Microsoft to wield undue influence . The article further says that Microsoft was accused of co-opting the standardization process by leaning on countries to ensure that it got enough votes at the ISO for Office Open XML to pass , although it does not specify exactly who accused Microsoft . Richard Stallman of the Free Software Foundation has stated that `` Microsoft offers a gratis patent license for OOXML on terms which do not allow free implementations . '' Licensing ( edit ) Under the Ecma International code of conduct in patent matters , participating and approving member organisations of ECMA are required to make available their patent rights on a reasonable and non-discriminatory ( RAND ) basis . Holders of patents which concern ISO / IEC International Standards may agree to a standardized license governing the terms under which such patents may be licensed , in accord with the ISO / IEC / ITU common patent policy . Microsoft , the main contributor to the standard , provided a covenant not to sue for its patent licensing . The covenant received a mixed reception , with some like the Groklaw blog criticizing it , and others such as Lawrence Rosen , ( an attorney and lecturer at Stanford Law School ) , endorsing it . Microsoft has added the format to their Open Specification Promise in which Microsoft irrevocably promises not to assert any Microsoft Necessary Claims against you for making , using , selling , offering for sale , importing or distributing any implementation to the extent it conforms to a Covered Specification ( ... ) This is limited to applications which do not deviate from the ISO / IEC 29500 : 2008 or Ecma - 376 standard and to parties that do not `` file , maintain or voluntarily participate in a patent infringement lawsuit against a Microsoft implementation of such Covered Specification '' . The Open Specification Promise was included in documents submitted to ISO / IEC in support of the ECMA - 376 fast - track submission . Ecma International asserted that , `` The OSP enables both open source and commercial software to implement ( the specification ) '' . Versions ( edit ) The Office Open XML specification exists in a number of versions . ECMA - 376 1st edition ( 2006 ) ( edit ) The ECMA standard is structured in five parts to meet the needs of different audiences . Part 1 . Fundamentals Vocabulary , notational conventions and abbreviations Summary of primary and supporting markup languages Conformance conditions and interoperability guidelines Constraints within the Open Packaging Conventions that apply to each document type Part 2 . Open Packaging Conventions The Open Packaging Conventions ( OPC ) , for the package model and physical package , is defined and used by various document types in various applications from multiple vendors . It defines core properties , thumbnails , digital signatures , and authorizations & encryption capabilities for parts or all of the contents in the package . XML schemas for the OPC are declared as XML Schema Definitions ( XSD ) and ( non-normatively ) using RELAX NG ( ISO / IEC 19757 - 2 ) Part 3 . Primer Informative ( non-normative ) introduction to WordprocessingML , SpreadsheetML , PresentationML , DrawingML , VML and Shared MLs , providing context and illustrating elements through examples and diagrams Describes the custom XML data - storing facility within a package to support integration with business data Part 4 . Markup Language Reference Contains the reference material for WordprocessingML , SpreadsheetML , PresentationML , DrawingML , Shared MLs and Custom XML Schema , defining every element and attribute including the element hierarchy ( parent / child relationships ) XML schemas for the markup languages are declared as XSD and ( non-normatively ) using RELAX NG Defines the custom XML data - storing facility Part 5 . Markup Compatibility and Extensibility Describes extension facilities of OpenXML documents and specifies elements & attributes through which applications can operate across different extensions . Later versions of the ECMA - 376 standard are aligned and technically equivalent to the corresponding ISO standard . ISO / IEC 29500 : 2008 ( edit ) The ISO / IEC standard is structured into four parts : Parts 1 , 2 and 3 are independent standards ; for example , Part 2 , specifying Open Packaging Conventions , is used by other file formats including XPS and Design Web Format . Part 4 is to be read as a modification to Part 1 , which it requires . A technically equivalent set of texts is also published by Ecma as ECMA - 376 2nd edition ( 2008 ) . Part 1 . Fundamentals & Markup Language Reference Consisting of 5560 pages , this part contains : Conformance definitions Reference material for the XML document markup languages defined by the Standard XML schemas for the document markup languages declared using XSD and ( non-normatively ) RELAX NG Defines the foreign markup facilities Part 2 . Open Packaging Conventions Consisting of 129 pages , this part contains : A description of the Open Packaging Conventions ( package model , physical package ) Core properties , thumbnails and digital signatures XML schemas for the OPC are declared using XSD and ( non-normatively ) RELAX NG Part 3 . Markup Compatibility and Extensibility Consisting of 40 pages , this part contains : A description of extensions : elements & attributes which define mechanisms allowing applications to specify alternative means of negotiating content Extensibility rules are expressed using NVDL Part 4 . Transitional Migration Features Consisting of 1464 pages , this part contains : Legacy material such as compatibility settings and the graphics markup language VML A list of syntactic differences between this text and ECMA - 376 1st Edition The standard specifies two levels of document & application conformance , strict and transitional , for each of WordprocessingML , PresentationML and SpreadsheetML , and also specifies applications ' descriptions of base and full . Compatibility between versions ( edit ) The intent of the changes from ECMA - 376 1st Edition to ISO / IEC 29500 : 2008 was that a valid ECMA - 376 document would also be a valid ISO 29500 Transitional document ; however , at least one change introduced at the BRM -- refusing to allow further values for xsd : boolean -- had the effect of breaking backwards - compatibility for most documents . A fix for this had been suggested to ISO / IEC JTC1 / SC34 / WG4 , and was approved in June 2009 as a recommendation for the first revision to Office Open XML . Applications capable of reading documents compliant to ECMA - 376 Edition 1 would regard ISO / IEC 29500 - 4 Transitional documents containing ISO 8601 dates as corrupt . Application support ( edit ) Main article : List of software that supports Office Open XML Some older versions of Microsoft Word and Microsoft Office are able to read and write . docx files after installation of the free compatibility pack provided by Microsoft , although some items , such as equations , are converted into images that can not be edited . Starting with Microsoft Office 2007 , the Office Open XML file formats have become the default file format of Microsoft Office . However , due to the changes introduced in the Office Open XML standard , Office 2007 is not wholly in compliance with ISO / IEC 29500 : 2008 . Office 2010 includes support for the ISO / IEC 29500 : 2008 - compliant version of Office Open XML , but it can only save documents conforming to the transitional , not the strict , schemas of the specification . Note that the intent of the ISO / IEC is to allow the removal of the transitional variant from the ISO / IEC 29500 standard . The ability to read and write Office Open XML format is , however , not limited to Microsoft Office ; other office products are also able to read & write this format : SoftMaker Office 2010 is able to read and write DOCX and XLSX files in its word processor & spreadsheet applications . LibreOffice is able to open and save Office Open XML files . OpenOffice.org and Apache OpenOffice from version 3.0 has been able to import Office Open XML files , but not save them . Version 3.2 improved this feature with read support even for password - protected Office Open XML files . The Go - oo fork of OpenOffice could also write OOXML files . KOffice from version 2.2 and later was able to import OOXML files . Calligra Suite is able to import Office Open XML files . NeoOffice , an OpenOffice.org fork for OS X is able to import but not save OOXML . Other office products that offer import support for the Office Open XML formats include : TextEdit ( included with OS X ) iWork IBM Lotus Notes Abiword WordPerfect Kingsoft Office Google Docs SoftMaker FreeOffice See also ( edit ) OOXML technical specification Standardization of Office Open XML Microsoft Word and Excel password protection Open Document Format ( ODF ) List of document markup languages Comparison of document markup languages References ( edit ) ^ Jump up to : Microsoft . `` Register file extensions on third party servers '' . microsoft.com .

The format was initially standardized by Ecma ( as ECMA - 376 ) , and by the ISO and IEC ( as ISO / IEC 29500 ) in later versions . Starting with Microsoft Office 2007 , the Office Open XML file formats have become the default target file format of Microsoft Office . Microsoft Office 2010 provides read support for ECMA - 376 , read / write support for ISO / IEC 29500 Transitional , and read support for ISO / IEC 29500 Strict . Microsoft Office 2013 and Microsoft Office 2016 additionally support both reading and writing of ISO / IEC 29500 Strict . In 2000 , Microsoft released an initial version of an XML - based format for Microsoft Excel , which was incorporated in Office XP . In 2002 , a new file format for Microsoft Word followed . The Excel and Word formats -- known as the Microsoft Office XML formats -- were later incorporated into the 2003 release of Microsoft Office . Microsoft announced in November 2005 that it would co-sponsor standardization of the new version of their XML - based formats through Ecma International as `` Office Open XML '' . The presentation was made to Ecma by Microsoft 's Jean Paoli and Isabelle Valet - Harper . Microsoft submitted initial material to Ecma International Technical Committee TC45 , where it was standardized to become ECMA - 376 , approved in December 2006 . This standard was then fast - tracked in the Joint Technical Committee 1 of ISO and IEC . After initially failing to pass , an amended version of the format received the necessary votes for approval as an ISO / IEC Standard as the result of a JTC 1 fast - tracking standardization process that concluded in April 2008 . The resulting four - part International Standard ( designated ISO / IEC 29500 : 2008 ) was published in November 2008 and can be downloaded from the ITTF . A technically equivalent set of texts is published by Ecma as ECMA - 376 Office Open XML File Formats -- 2nd edition ( December 2008 ) ; they can be downloaded from their web site . The ISO standardization of Office Open XML was controversial and embittered , with much discussion both about the specification and about the standardization process . According to InfoWorld : OOXML was opposed by many on grounds it was unneeded , as software makers could use OpenDocument Format ( ODF ) , a less complicated office software format that was already an international standard . The same InfoWorld article reported that IBM ( which supports the ODF format ) threatened to leave standards bodies that it said allow dominant corporations like Microsoft to wield undue influence . The article further says that Microsoft was accused of co-opting the standardization process by leaning on countries to ensure that it got enough votes at the ISO for Office Open XML to pass , although it does not specify exactly who accused Microsoft . Richard Stallman of the Free Software Foundation has stated that `` Microsoft offers a gratis patent license for OOXML on terms which do not allow free implementations . '' Under the Ecma International code of conduct in patent matters , participating and approving member organisations of ECMA are required to make available their patent rights on a reasonable and non-discriminatory ( RAND ) basis . Holders of patents which concern ISO / IEC International Standards may agree to a standardized license governing the terms under which such patents may be licensed , in accord with the ISO / IEC / ITU common patent policy . Microsoft , the main contributor to the standard , provided a covenant not to sue for its patent licensing . The covenant received a mixed reception , with some like the Groklaw blog criticizing it , and others such as Lawrence Rosen , ( an attorney and lecturer at Stanford Law School ) , endorsing it . Microsoft has added the format to their Open Specification Promise in which Microsoft irrevocably promises not to assert any Microsoft Necessary Claims against you for making , using , selling , offering for sale , importing or distributing any implementation to the extent it conforms to a Covered Specification ( ... ) This is limited to applications which do not deviate from the ISO / IEC 29500 : 2008 or Ecma - 376 standard and to parties that do not `` file , maintain or voluntarily participate in a patent infringement lawsuit against a Microsoft implementation of such Covered Specification '' . The Open Specification Promise was included in documents submitted to ISO / IEC in support of the ECMA - 376 fast - track submission . Ecma International asserted that , `` The OSP enables both open source and commercial software to implement ( the specification ) '' . The Office Open XML specification exists in a number of versions . The ECMA standard is structured in five parts to meet the needs of different audiences . Part 1 . Fundamentals Vocabulary , notational conventions and abbreviations Summary of primary and supporting markup languages Conformance conditions and interoperability guidelines Constraints within the Open Packaging Conventions that apply to each document type Part 1 .

Later versions of the ECMA - 376 standard are aligned and technically equivalent to the corresponding ISO standard . The ISO / IEC standard is structured into four parts : Parts 1 , 2 and 3 are independent standards ; for example , Part 2 , specifying Open Packaging Conventions , is used by other file formats including XPS and Design Web Format . Part 4 is to be read as a modification to Part 1 , which it requires . A technically equivalent set of texts is also published by Ecma as ECMA - 376 2nd edition ( 2008 ) . Part 1 .

Transitional Migration Features Consisting of 1464 pages , this part contains : Legacy material such as compatibility settings and the graphics markup language VML A list of syntactic differences between this text and ECMA - 376 1st Edition Legacy material such as compatibility settings and the graphics markup language VML A list of syntactic differences between this text and ECMA - 376 1st Edition Legacy material such as compatibility settings and the graphics markup language VML A list of syntactic differences between this text and ECMA - 376 1st Edition The standard specifies two levels of document & application conformance , strict and transitional , for each of WordprocessingML , PresentationML and SpreadsheetML , and also specifies applications ' descriptions of base and full . The intent of the changes from ECMA - 376 1st Edition to ISO / IEC 29500 : 2008 was that a valid ECMA - 376 document would also be a valid ISO 29500 Transitional document ; however , at least one change introduced at the BRM -- refusing to allow further values for xsd : boolean -- had the effect of breaking backwards - compatibility for most documents . A fix for this had been suggested to ISO / IEC JTC1 / SC34 / WG4 , and was approved in June 2009 as a recommendation for the first revision to Office Open XML . Applications capable of reading documents compliant to ECMA - 376 Edition 1 would regard ISO / IEC 29500 - 4 Transitional documents containing ISO 8601 dates as corrupt . Some older versions of Microsoft Word and Microsoft Office are able to read and write . docx files after installation of the free compatibility pack provided by Microsoft , although some items , such as equations , are converted into images that can not be edited . Starting with Microsoft Office 2007 , the Office Open XML file formats have become the default file format of Microsoft Office . However , due to the changes introduced in the Office Open XML standard , Office 2007 is not wholly in compliance with ISO / IEC 29500 : 2008 . Office 2010 includes support for the ISO / IEC 29500 : 2008 - compliant version of Office Open XML , but it can only save documents conforming to the transitional , not the strict , schemas of the specification . Note that the intent of the ISO / IEC is to allow the removal of the transitional variant from the ISO / IEC 29500 standard . The ability to read and write Office Open XML format is , however , not limited to Microsoft Office ; other office products are also able to read & write this format : SoftMaker Office 2010 is able to read and write DOCX and XLSX files in its word processor & spreadsheet applications . LibreOffice is able to open and save Office Open XML files . OpenOffice.org and Apache OpenOffice from version 3.0 has been able to import Office Open XML files , but not save them . Version 3.2 improved this feature with read support even for password - protected Office Open XML files . The Go - oo fork of OpenOffice could also write OOXML files . KOffice from version 2.2 and later was able to import OOXML files . Calligra Suite is able to import Office Open XML files . NeoOffice , an OpenOffice.org fork for OS X is able to import but not save OOXML . SoftMaker Office 2010 is able to read and write DOCX and XLSX files in its word processor & spreadsheet applications . LibreOffice is able to open and save Office Open XML files .
