Convert GNM to UOS

The GNM file extension, short for Gnumeric, is used by the Gnumeric spreadsheet application, part of the GNOME Desktop Software. It stores spreadsheet data in rows and columns, supports charts, and other functionalities. GNM files are compressed XML files, similar to XLSX, and can be decompressed using standard utilities like WinZIP. Gnumeric aims to provide an open-source alternative to Microsoft Excel.

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.
