Convert WB1 to XLS (Excel)

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 XLS file extension, short for "Excel Spreadsheet", is a legacy format used by Microsoft Excel for storing spreadsheet data. Introduced with Excel 2.0 in 1987, it was the primary format until the introduction of XLSX in 2007. XLS files contain data organized in rows and columns, supporting formulas, macros, and various formatting options, making them essential for data analysis and financial reporting. Despite being replaced by the more robust and secure XLSX format, XLS files remain widely used in many legacy systems and applications.
