I have lots of .wpd files I can’t open on my Mac that need to be converted to either .docx or .rtf.
And not interested in installing Parallels or a similar Windows shell on the Mac.
Have you tried searching to see whether this question has been asked before? For example Is it possible to open Word Perfect Documents using LibreOffice on a MAC?
I did. Related questions were addressed - e.g., it seemed clear the files could be opened in Windows but whether this is true on a Mac wasn’t mentioned.
We would not normally distinguish between the data functions supported on Linux, windows or even a mac. The look, of course will be different, as the ease of switching languages.
