Use Lotus 1-2-3 version 4.x or later to open the *.wk3 files.
Also some modern spreadsheets programs can still open the *.wk4 files. However the latest versions of Microsoft Excel from 2007 no longer support that format. You can have luck with any earlier version of Excel, but you will probably lose most of the formatting from the .wk4 files.
You can open *.wk4 in Microsoft Excel and save it to another file format. You will probably lose formatting.
