wk4 to wk1 conversion is most likely related to conversion between two old Lotus 1-2-3 spreadsheets, something that will be very hard to achieve with modern software. Your best choice for this (for whatever reason you want it) would be to find some old version of Excel or something like that. But overall the chances that modern software can work with old Lotus 1-2-3 files are pretty low.
