The most reliable way how to work with ancient Lotus 1-2-3 spreadsheets (.wk1, .wk!, etc.) would be to use the original tool, perhaps in a virtual machine. If you do not have access to the original tool, you have to use some 3rd party software for the job, for example some open source productivity suites that may still support old Lotus 1-2-3 formats.

The tables with software actions are a good pointer for what a certain program does with various file types and often may give users a good hint how to perform certain file conversion, for example the above-mentioned wk! to wk1. However, it is not perfect and sometimes can show results which are not really usable because of how certain programs work with files and the possible conversion is thus actually not possible at all.
