Programmatic support, filters, converters
There are OpenDocument-oriented libraries available for languages such as Java, Python, Ruby, C++ and C#. OpenDoc Society maintains an extensive list of ODF software libraries for OpenDocument Format.

OpenDocument packages are ordinary zip files. There is an OpenDocument format which is just a single XML file, but most applications use the package format. Thus, any of the vast number of tools for handling zip files and XML data can be used to handle OpenDocument.  Nearly all programming languages have libraries (built-in or available) for processing XML files and zip files.

Microsoft
Microsoft has been offering native support for ODF since Office 2007 Service Pack 2. Microsoft is hosting the 8th ODF Plugfest in Brussels in 2012.

In October 2005, one year before the Microsoft Office 2007 suite was released, Microsoft declared that there is not sufficient demand from Microsoft customers for international standard OpenDocument format support and therefore it will not be included in Microsoft Office 2007. This statement was repeated also in next months. As an answer, on 20 October 2005 an online petition was created to demand ODF support from Microsoft. The petition was signed by circa 12000 people.

In May 2006, ODF plugin for Microsoft Office was released by OpenDocument Foundation. Microsoft declared that the company did not work with the developers of the plug-in.

In July 2006 Microsoft announced the creation of the Open XML Translator project—tools to build a technical bridge between the Microsoft Office Open XML Formats and the OpenDocument Format (ODF). This work was started in response to government requests for interoperability with ODF. The goal of project is not to implement ODF direct to Microsoft Office, but only to create plugin and external tools. In February 2007, this project released first version of ODF plug-in for Microsoft Word.

In February 2007 SUN released initial version of SUN ODF plugin for Microsoft Office. Version 1.0 was released in July 2007.

Microsoft Office 2007 Service Pack 2 was released on 28 April 2009. It added native support of OpenDocument 1.1 as well as other formats like XPS and PDF.

In April 2012, Microsoft announced support for ODF 1.2 in Microsoft Office 2013.

Microsoft has financed the creation of an Open XML translator, to enable the conversion of documents between Office Open XML and OpenDocument. The project, hosted on SourceForge, is an effort by several of Microsoft's partners to create a plugin for Microsoft Office that will be freely available under a BSD license. By December 2007, plugins had been released for Microsoft Word, Microsoft Excel and Microsoft PowerPoint. Independent analysis has, however, reported several concerns with these plugins, including lack of support for Office 2007.

Third party support: Two ODF plug-ins for Microsoft Office
There are currently two third-party plug-ins:
Sun Microsystems' ODF Plugin for Microsoft Office users (download link no longer available as of 30 March 2013)— gives users of Microsoft Office Word, Excel and PowerPoint the ability to read, edit and save to the ISO-standard Open Document Format (ODF). It works with Microsoft Office 2007 (with service pack 1 or higher), Microsoft Office 2003, Microsoft Office XP, and even Microsoft Office 2000.
ooo-word-filter — enables users of Microsoft Word 2003 to open OpenDocument files.

A third plug-in, OpenOpenOffice (O3), is apparently inactive. OpenOpenOffice was developed by Phase-n, a free and open source software plug-in to enable Microsoft Office to read and write OpenDocument files (and any other formats supported by OpenOffice.org). Instead of installing a complete office application or even a large plug-in, O3 intended to install a tiny plug-in to the Microsoft Office system. This tiny plug-in intended to automatically send the file to some server, which would then do the conversion, returning the converted file. The server could be local to an organization (so private information doesn't go over the Internet) or accessed via the Internet (for those who do not want to set up a server). A beta of the server half has been completed, and further expected announcements have not occurred. Phase-n argued that the main advantage of their approach is simplicity. Their website announces that O3 "requires no new concepts to be explored, no significant development, and leverages the huge existing body of work already created by the OpenOffice developers, the CPAN module authors, and the Microsoft .NET and Office teams. They also argue that this approach significantly simplifies maintenance; when a new version of OpenOffice is released, only the server needs to be upgraded.

A fourth plug-in was announced by the OpenDocument Foundation in May 2006 but development was stopped in October 2007.

Microsoft Office 2007 SP2 support controversy
Microsoft supports OpenDocument format in Office 2007 SP2. The current implementation faces criticism for not supporting encrypted documents and formula format in the same way as other OpenDocument-compatible software, as well as for stripping out formulas in imported spreadsheets created by other OpenDocument-compatible software. Critics say that with this conflict of standards Microsoft actually managed to reduce interoperability between office productivity software. The company had previously reportedly stated that "where ODF 1.1 is ambiguous or incomplete, the Office implementation can be guided by current practice in OpenOffice.org, mainly, and other implementations including KOffice and AbiWord. Peter Amstein and the Microsoft Office team are reluctant to make liberal use of extension mechanisms, even though provided in ODF 1.1. They want to avoid all appearance of an embrace-extend attempt." However, according to the ODF Alliance, "ODF spreadsheets created in Excel 2007 SP2 do not in fact conform to ODF 1.1 because Excel 2007 incorrectly encodes formulas with cell addresses. Section 8.3.1 of ODF 1.1 says that addresses in formulas "start with a "[" and end with a "]"." In Excel 2007 cell addresses were not enclosed with the necessary square brackets, which could be easily corrected." This however has been contested as the ISO/IEC 26300 specification states that the semantics and the syntax is dependent on the used namespace which is implementation dependent leaving the syntax implementation defined as well.

Before SP2, Microsoft had sponsored the creation of the Open XML translator project to allow the conversion of documents between OOXML and OpenDocument. As a result of this project, Microsoft financed the ODF add-in for Word project on SourceForge. This project is an effort by several of Microsoft's partners to create a plugin for Microsoft Office that will be freely available under a BSD license. The project released version 1.0 for Microsoft Word of this software in January 2007 followed by versions for Microsoft Excel and Microsoft PowerPoint in December of the same year. Sun Microsystems has created the competing OpenDocument plugin for Microsoft Office 2007 (Service Pack 1 or higher), 2000, XP, and 2003 that supports Word, Excel, and PowerPoint documents.
The ODF Alliance has claimed that third-party plug-ins "provide better support for ODF than the recently released
Microsoft Office 2007 SP2".

Dynamic languages

Some open source application programming interfaces, designed for OpenDocument handling, are available in various dynamic programming languages such as Perl and Python. The Lpod project is an example.

Accessibility
One important issue raised in the discussion of OpenDocument is whether the format is accessible to those with disabilities. There are two issues: does the specification support accessibility, and are implementations accessible?

Specification
While the specification of OpenDocument is going through an extensive accessibility review, many of the components it is built on (such as SMIL for audio and multimedia and SVG for vector graphics) have already gone through the World Wide Web Consortium (W3C)'s Web Accessibility Initiative processes.

There are already applications that currently read/write OpenDocument that export Tagged PDF files (to support PDF accessibility); this suggests that much or all of the necessary data for accessibility is already included in the OpenDocument format.

The OASIS OpenDocument technical committee released a draft of OpenDocument 1.1 on 2006-07-27, for public comment through 2006-09-25.
This is a very minor update to the specification to add accessibility information, mainly soft page break markings, table header markings, presentation navigation markings, alternative text and captions, and specifically stating that spreadsheets may be embedded in presentations.
Peter Korn (an accessibility expert) reviewed version 1.1 "to satisfy myself that all of our accessibility concerns have been addressed", and declared "I am so satisfied."

Implementations
Peter Korn gave an in-depth report on OpenDocument accessibility. He noted that there are many kinds of impairments, including visual (minor, major, or blind), physical (minor, major with vocal control, major without vocal control), auditory, and cognitive. He then noted that the situation varies, depending on the specific disability. For a vast number of disabilities, there are no known problems, though.

 OpenOffice is expected to work well with existing solutions in MS Windows' on-screen keyboards (etc.) when driven by single-switch access, head-mouse, and eye-gaze systems.  On Unix-like systems, GNOME's "On-screen Keyboard" can be used. Also available on both Linux and Windows systems is Dasher, a text-entry alternative released under the GPL for head-mouse and eye-gaze users (35+ word-per-minute typing speeds using nothing but eye movement are possible).
 If those with disabilities are already using Microsoft Office, then a plug-in enabling them to load and save OpenDocument files using Microsoft Office may give them the same capabilities they already have (assuming the opening/saving cycle is accessible).  So from that perspective, OpenDocument is at least as accessible as Microsoft Office.
 For users using alternatives to Microsoft Office there may be problems, not necessarily due to the ODF file format but rather due to the lower investment to date by assistive technology vendors on these platforms, though there is ongoing work. For example, IBM has stated that its "Workplace productivity tools available through Workplace Managed Client including word processing, spreadsheet and presentation editors are currently planned to be fully accessible on a Windows platform by 2007. Additionally, these productivity tools are currently planned to be fully accessible on a Linux platform by 2008" (Sutor, 10 November 2005).

It is important to note that since OpenDocument is an Open Standard file format, there is no need for everyone to use the same program to read and write OpenDocument files; someone with a disability is free to use whatever program works best for them.
