Convert WK1 to XLSX

---

Data from old Lotus 1-2-3 spreadsheets (.wk1 files) can be perhaps still imported to Microsoft Excel or similar spreadsheet editor and  the imported data saved in some modern format, for example Excel's XLSX spreadsheets. It is very likely that no formatting will be converted, just data, but wk1 to xlsx conversion should be doable.
