The file extension UOF identifies the uniform office format. This format was developed as an open standard in China for office applications. The standard includes word processing, spreadsheet and presentation modules as well as the specifications for the GUI (graphical user interface, API (application interfaces) and file formats.
The UOF files are XML-based and resemble OpenDocument and Office Open XML files.
The files can contain text documents, tables or presentations, although for each of these file types also own endings exist.
