This works somewhat, but doesn't handle ChatGPT mathematical equations well. On the other hand, nothing else I've tried does either. My rating of 3 means "pretty much average."

What works best for me is the following sequence: 1) Select all 2) Copy 3) Paste into an empty writer document. (I've only tried OpenOffice's and LibreOffice's writers.)

Both writers fail in the same way. In my particular test case they miss a fraction operation.

ChatGPT tells me it doesn't use LaTeX natively, so I need to ask it to convert equations into LaTeX, then copy/paste to replace the bollixed equation in the document. This is too much of a bother so I thought I'd give Print Friendly a try.
