Convert ET to UOS

The ET file extension is associated with Kingsoft Spreadsheets, part of the WPS Office suite. It is used to store and organize financial data, such as balance sheets, expense statements, and invoices, in a format of rows and columns. The ET file supports formulas and charts, and it can be converted to more common formats like XLS or XLSX. The WPS Office suite, similar to Microsoft Office, offers tools for word processing, spreadsheets, and presentations.

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.
