Convert XLW to UOS

The XLW file extension stands for Microsoft Excel Workspace, a format used by Microsoft Excel to save the screen locations of multiple open workbooks, allowing users to restore their layout upon reopening. Introduced in earlier versions of Excel, this feature was discontinued from Excel 2013 onwards, though existing XLW files can still be opened. The primary use of XLW files was to enhance productivity by maintaining an organized workspace with multiple workbooks.

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.
