Convert FODS to UOS

The FODS (OpenDocument Flat XML Spreadsheet) file extension, developed by Oracle, is used for storing spreadsheet data in a plain XML format, making it more human-readable and easier to generate automatically without a spreadsheet editor. Unlike the more common ODS format, which uses a ZIP container, FODS files are not supported by Microsoft Excel but can be opened with OpenOffice Calc. This format was introduced as part of the ODF 1.2 specifications by OASIS.

The UOS (Uniform Office Spreadsheet) file extension is used for spreadsheets created in the Uniform Office Format (UOF), a Chinese-developed open standard for office productivity applications. Introduced in 2007, UOS files save data using XML and compression, making them similar to but not compatible with Microsoft Office Open XML and OASIS OpenDocument formats. These files can be opened by applications like OpenOffice Calc.
