Convert WB2 to XLS

wb2 to xls conversion pretty much describes the export of data from old Quattro Pro spreadsheets to MS Excel format, something that might be doable, albeit a little tricky nowadays. The best course of action would be to find some old version of Quattro Pro or some software that supports Quattro Pro's formats, export the spreadsheet to CSV or similar format and import that to Excel. Except for that, it is unlikely that some utility that can be used to convert wb2 to xls exists.
