'''Office Open XML'''（縮寫：'''Open XML'''、'''OpenXML'''或'''OOXML'''），為由[[Microsoft]]開發的一種以[[XML]]為基礎並以[[ZIP格式]]壓縮的電子文件規範，支持[[文件]]、[[表格]]、[[備忘錄]]、[[演示文稿|幻燈片]]等檔案格式。

OOXML在[[2006年12月]]成為了[[ECMA]]規範的一部分，編號為ECMA-376；並於[[2008年4月]]通過[[國際標準化組織]]的表決，在兩個月後公佈為[[ISO]]／[[IEC]] 29500國際標準。微軟推出這個格式，很多人認為是出於商業考量。<ref>{{cite web |url=http://www.builder.com.cn/2008/0227/743476.shtml |title=Linux基金会：微软推OOXML的理由很荒唐 |publisher=开发者在线 |date=2008-02-27 |accessdate=2013-03-08 |archive-date=2008-10-10 |archive-url=https://web.archive.org/web/20081010172440/http://www.builder.com.cn/2008/0227/743476.shtml |dead-url=no }}</ref>許多專家指出，該標準並不是個完整的標準，採用了許多[[微軟]]的獨有規格，使用上困難重重。<ref>{{cite web |url=http://tech.qq.com/a/20070822/000203.htm |title=共创联盟报告指微软文档标准有20大问题 |publisher=腾讯科技 |date=2007-08-22 |accessdate=2013-03-08 |archive-date=2013-10-29 |archive-url=https://web.archive.org/web/20131029210844/http://tech.qq.com/a/20070822/000203.htm |dead-url=no }}</ref><ref>{{cite web |url=http://www.ibm.com/developerworks/xml/library/x-ooxmlstandard/index.html |title=OOXML: What's the big deal? |publisher=IBM developerWorks |date=19 Feb 2008 |deadurl=yes |archiveurl=https://web.archive.org/web/20120126151924/http://www.ibm.com/developerworks/xml/library/x-ooxmlstandard/index.html |archivedate=2012-01-26 |accessdate=2013-03-08 }}</ref>

从Microsoft Office 2007开始，Office Open XML文件格式已经成为Microsoft Office默认的文件格式。<ref name="microsoft.com">{{cite web | url = http://www.microsoft.com/Presspass/press/2008/may08/05-21ExpandedFormatsPR.mspx?rss_fdn=Press%20Releases | title = Microsoft Expands List of Formats Supported in Microsoft Office | publisher = Microsoft | accessdate = 2008-05-21 | deadurl = yes | archiveurl = https://web.archive.org/web/20090715092036/http://www.microsoft.com/Presspass/press/2008/may08/05-21ExpandedFormatsPR.mspx?rss_fdn=Press%20Releases | archivedate = 2009-07-15 }}</ref><ref name="courierpress.com">{{cite web | url = http://www.courierpress.com/news/2008/oct/24/microsofts-future-lies-somewhere-beyond-the/ | title = Microsoft's future lies somewhere beyond the Vista by Evansville Courier & Press | publisher = Courierpress.com | accessdate = 2009-05-19 | archive-date = 2014-07-10 | archive-url = https://web.archive.org/web/20140710192710/http://www.courierpress.com/news/2008/oct/24/microsofts-future-lies-somewhere-beyond-the/ | dead-url = no }}</ref><ref name="knowledge.wharton.upenn.edu">{{cite web | url = http://knowledge.wharton.upenn.edu/article.cfm?articleid=1795 | title = Rivals Set Their Sights on Microsoft Office: Can They Topple the Giant? - Knowledge@Wharton | publisher = Knowledge.wharton.upenn.edu | accessdate = 2009-05-19 | archive-date = 2007-08-30 | archive-url = https://web.archive.org/web/20070830001652/http://knowledge.wharton.upenn.edu/article.cfm?articleid=1795 | dead-url = no }}</ref>Microsoft Office 2010支持对ECMA-376标准文档的读操作，ISO/IEC 29500 Transitional的读/写，ISO/IEC 29500 Strict的读取。<ref>{{Cite web |url=http://technet.microsoft.com/en-us/library/cc179190.aspx |title=Overview of the XML file formats in Office 2010 |accessdate=2013-03-08 |archive-date=2012-11-18 |archive-url=https://web.archive.org/web/20121118033038/http://technet.microsoft.com/en-us/library/cc179190.aspx |dead-url=no }}</ref>Microsoft Office 2013同时支持ISO/IEC 29500 Strict的读写操作。<ref name="Doug Mahugh blog">{{cite web | url = http://blogs.msdn.com/b/dmahugh/archive/2010/04/06/office-s-support-for-iso-iec-29500-strict.aspx | title = Office’s Support for ISO/IEC 29500 Strict | author = Doug Mahugh | publisher = MSDN blogs | accessdate = 2011-02-18 | archive-date = 2010-12-02 | archive-url = https://web.archive.org/web/20101202145136/http://blogs.msdn.com/b/dmahugh/archive/2010/04/06/office-s-support-for-iso-iec-29500-strict.aspx | dead-url = no }}</ref>

它的競爭對手是[[OpenDocument Format]]，後者是被廣泛接受的一種開放的文檔存儲和交換規範。

== 版本 ==
存在以下几个版本的Office Open XML标准。

===ECMA 376===
ECMA 376，目前歷經4個版本，第1版（2006年12月）、第2版（2008年12月）、第3版（2011年6月）、第4版（2012年12月）。<ref name="StandardECMA376">{{cite web | url = http://www.ecma-international.org/publications/standards/Ecma-376.htm | title = Standard ECMA-376 | publisher = Ecma-international.org | accessdate = 2009-05-19 | archive-date = 2011-08-24 | archive-url = https://www.webcitation.org/61AUEJn1S?url=http://www.ecma-international.org/publications/standards/Ecma-376.htm | dead-url = no }}</ref>

=== ISO/IEC 29500 ===
ISO/IEC 29500目前最新的版本為2012年的版本
ISO/IEC标准的结构分为四部分。第1、2和3是独立的标准，第2部分用于其他文件格式，包括[[Design_Web_Format]]和[[XML纸张规范|XPS格式]]。第4部分作用是读出第1部分的变体。<ref name="StandardIS29500">{{cite web| url=http://www.iso.org/iso/search.htm?qt=29500&published=on&active_tab=standards| title=ISO search for "29500"| publisher=[[International Organization for Standardization]]| date=2009-06-05| accessdate=2013-03-08| archive-date=2013-03-08| archive-url=https://web.archive.org/web/20130308121820/http://www.iso.org/iso/search.htm?qt=29500&published=on&active_tab=standards| dead-url=no}}</ref>
*第1部分（基础知识和标记语言参考）
*第2部分（解包约定）
*第3部分（标记兼容性和可扩展性）
*第4部分（过渡期迁移特性）

== 批評 ==
微軟公司發表的Office Open XML使用許多非標準的規範，造成與其他辦公室軟體（例如[[LibreOffice]]）讀取時發生不相容或內容偏移的情形，目的是讓[[Microsoft Office]]保持市場優勢。

[[ODF]](廣泛接受的開放文檔規範)編碼時會使用其他標準規範(如[[ISO 639]]、[[MathML]])來進行儲存，但OOXML使用非標準的編碼進行存取。例如 ODF 裡面的顏色代碼，不管是試算表、文件、簡報等，紅色的代碼都是 #FF0000，然而在OOXML裏隨不同產品，代碼分別為：
*Word：#FF0000
*Excel：#FFFF0000
*Powerpoint：#FF0000

OOXML設計的目的是將微軟定義的 doc、ppt、xls 二進制格式轉成 XML 格式，並沒有依照 XML 的特性最佳化，而其私有格式內含的額外非標準元件也包含在內，例如[[ActiveX]]等等（過時，且容易用於攻擊）；另一方面，[[比尔·盖茨]]在1998年留下的備忘錄提到「不能讓其他瀏覽器可完美顯示MS Office文件，只能讓自家公司的專屬[[Internet_Explorer|IE]]可正確顯示」，現在的狀況可以說是微軟延續了比爾·蓋茲的精神，使「現代的MS Office存出的OOXML檔」刻意做成第三方軟體不能完善地解讀、呈現，顯示OOXML並非如其所聲稱的開放。<ref>{{Cite web |url=https://technews.tw/2017/08/16/the-big-secret-of-ooxml/ |title=微軟文書格式為何常跑掉？揭開 OOXML 格式大祕辛 |accessdate=2017-10-18 |archive-date=2017-10-19 |archive-url=https://web.archive.org/web/20171019005008/https://technews.tw/2017/08/16/the-big-secret-of-ooxml/ |dead-url=no }}</ref>

== Open XML Format SDK ==
[[Microsoft]] Open XML Format [[SDK]]<ref>{{cite web|url=http://msdn.microsoft.com/en-us/library/office/bb448854%28v=office.12%29.aspx|title=Open XML Format SDK|date=2008-06-10|author=Microsoft|publisher=Microsoft|accessdate=2019-06-24|archive-date=2017-10-08|archive-url=https://web.archive.org/web/20171008080621/https://msdn.microsoft.com/en-us/library/office/bb448854(v=office.12).aspx|dead-url=no}}</ref>包含一套[[托管代码]]库用于编程以创建、操纵Office Open XML文件。并不用于代替Microsoft Office Object Model，也不提供文件格式的顶层抽象。使用Open XML SDK必须理解文档格式结构。对Word文档不提供诸如layout功能；对Excel文档，不提供诸如重新计算、数据刷新等功能。

*版本1.0发布于2008年6月10日。<ref>{{cite web|url=http://blogs.msdn.com/erikaehrli/archive/2008/06/10/announcing-the-open-xml-format-sdk-1-0.aspx|title=Announcing the Open XML Format SDK 1.0|date=2008-06-10|author=Erika Ehrli|publisher=Computerworld|accessdate=2019-06-24|archive-date=2008-12-12|archive-url=https://web.archive.org/web/20081212224341/http://blogs.msdn.com/erikaehrli/archive/2008/06/10/announcing-the-open-xml-format-sdk-1-0.aspx|dead-url=no}}</ref>配合Office Open XML规范的ISO/IEC标准化过程。<ref name="ooxmlsdkroadmap">{{cite web|url=http://blogs.msdn.com/dmahugh/archive/2008/03/13/open-xml-sdk-roadmap.aspx|author=Doug Mahugh|publisher=MSDN Blogs|title=Open XML SDK roadmap|accessdate=2008-03-23|archive-date=2008-03-20|archive-url=https://web.archive.org/web/20080320204533/http://blogs.msdn.com/dmahugh/archive/2008/03/13/open-xml-sdk-roadmap.aspx|dead-url=no}}</ref>
*版本2.0：用于.NET 3.5应用程序。支持使用.NET的强类型类来直接表示XML的element/attribute/value、使用Office Open XML schema验证Office Open XML文档、在Office Open XML文档中搜索。该SDK建于System.IO.Packaging API之上。使用了.NET Framework Language-Integrated Query (LINQ)技术用强类型。把很多操作Open XML packages封装为API，以简化使用。
*版本2.5：用于.NET 4.0应用程序。发布于2014年6月<ref>{{cite web|url=https://msdn.microsoft.com/en-us/library/office/bb448854.aspx|title=Welcome to the Open XML SDK 2.5 for Office|publisher=Microsoft|date=2015-03-10|accessdate=2017-10-07|archive-date=2017-10-08|archive-url=https://web.archive.org/web/20171008030907/https://msdn.microsoft.com/en-us/library/office/bb448854.aspx|dead-url=no}}</ref>并在[[GitHub]]上开源。<ref>{{Cite web |url=https://github.com/OfficeDev/Open-XML-SDK |title=Open-XML-SDK on github |accessdate=2019-06-24 |archive-date=2019-02-09 |archive-url=https://web.archive.org/web/20190209052743/https://github.com/OfficeDev/Open-XML-SDK |dead-url=no }}</ref>这是目前最高版本。支持Office 2013的一些新的类。读取 ISO/IEC 29500 Strict Format文档。

'''Open XML SDK 2.5 Productivity Tool for Microsoft Office'''提供许多特性，如给予文档内容产生Open XML SDK 2.5源代码，比较源与目标Open XML documents以产生源代码从源创建目标文档、验证文档、显示文档，ECMA376v1标准，Microsoft Office实现注解。

通常安装在 C:\Program Files (x86)\Open XML SDK\V2.5\。

一个Open XML文档包含多个文档部分（document part）。ZIP格式支持任意访问各个部分。例如，一个slide页面、Word文档中的comment，都是独立的文档部分。一个Open XML文档就是一个Open Packaging Conventions (OPC)包(package)。每个文档部分有个部分名字，由一系列segments或一个pathname组成，如"/word/theme/theme1.xml"。包的[Content_Types].xml部分，用于确定包中所有文档部分的内容类型。

===SpreadsheetML文档===
SpreadsheetML文档包含<code><workbook></code>元素，其内部包含<code><sheets></code>与<code><sheet></code>元素用于表示各个工作表。每个工作表被创建为一个独立的XML文件。一个spreadsheet文档还可以包含<code><nowiki><table></nowiki></code>、 <code><chartsheet></code>、 <code><pivotTableDefinition></code>等元素。

在命名空间DocumentFormat.OpenXML.Spreadsheet中定义了spreadsheet中重要的elements：
{| class="wikitable"
|-
