|Initial release||30 April 2007|

|Type of format||Document file format|
|Extended from||XML, SVG|
Uniform Office Format sometimes known as Unified Office Format (UOF) is an open standard for office applications developed in China. It includes word processing, presentation, and spreadsheet modules, and is made up of GUI, API, and format specifications. The document format described uses XML contained in a compressed file container, similar to OpenDocument and Office Open XML.
The working group that produced the standard was founded in January 2002, and the first draft of the specification was produced in December 2005. The group producing the standard is open, with 'open-door' meetings, equitable voting by ballots, and the standard's documentation is free.
Application support 
Office suites 
A number of applications support the Uniform Office Format; listed alphabetically they include:
- EIOffice 2009 is said to be based on UOF. It use binder files with file extension EIO (.eio). In latest version 5.0.1272.101 it doesn't open or save files with file extensions .uof, .uot, .uos or .uop. In documentation to EIOffice is information about possibility to publish documents in "Unit Office Format (XML)"[dead link]
- Go-oo from version 3 can open and save files in "Unified Office Format" with file extensions .uof, .uot, .uos, .uop (text, spreadsheet, presentation)
- OpenOffice.org from version 3 can open and save files in "Unified Office Format" with file extensions .uof, .uot, .uos, .uop (text, spreadsheet, presentation) (This also applies to version 3 of NeoOffice, a popular variant of OpenOffice for the Macintosh.)
- LibreOffice created as a fork of OpenOffice.org, can also open and save files in "Unified Office Format" with file extensions .uof, .uot, .uos, .uop (text, spreadsheet, presentation)
- RedOffice 4.0, a Chinese OpenOffice.org variant, can open and save files with file extension .uof,
- WPS Office 2009, a Chinese office suite very similar to Microsoft Office 2003 in terms of look and functionality, supports read and write of UOF format.
Filters and converters 
ODF to UOF 
OOXML to UOF 
Software is being developed at ACT (The Institute of Advanced Computing Technology) at Beihang University to convert from OOXML to UOF and vice versa.
Possibility of merging UOF and ODF 
At the "World Trade Organization IPRs Issues in Standardization" conference in Beijing (April 2007), convened by the Chinese Ministry of Commerce, the China State Intellectual Property Office (SIPO) and Sun Microsystems, Scott McNealy, the Chairman of Sun Microsystems called for a merger of OASIS/ISO's ODF and China's UOF. While both formats are open, there are significant technical challenges in achieving a merger, as the two formats have made different fundamental choices in how to describe documents.
A comparison document between ODF and UOF is available from the ODF-UOF project on SourceForge.
