Convert WB1 to UOS

The WB1 file extension is associated with Corel Quattro Pro, a spreadsheet program developed by Borland and later sold by Alludo. It was used in version 5 of the software, which predates the more recent QPW format. Quattro Pro files, including WB1, are used to store spreadsheets containing data, formulas, and charts. Historically, Quattro Pro competed with Lotus 1-2-3 and Microsoft Excel, offering unique features like tabbed sheets and larger worksheet sizes.

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.
