Uniform Office Spreadsheet (.uof)
The Uniform Office Format (UOF) for spreadsheets, is a Chinese open standard designed for office applications. UOF, first introduced in 2007, utilizes XML-based data and compression techniques to store information efficiently, akin to Microsoft Office Open XML and OASIS OpenDocument formats. Although not universally compatible with other formats, it is supported by various applications. This format aims to streamline the use of spreadsheets in a standardized and accessible manner.
