[OS X TeX] recommendations for .odt to .tex in 2020

[Arthur Snoke]

I use LibreOffice for .doc, .docx, and .odt files that I get from others or 
create, but greatly prefer the control I can get on formatting in LaTeX.  In the 
past I used rtf2latex2e, but even ten years ago I found it dated and hard to 
work with.

What is the best way today?

I am currently on 10.13 but probably have to go to 10.14 soon.

I tried Writer2LaTeX 1.6.1as an export filter and it bombed with an error 
message "Error saving the document...General Input Output Error"

None of the google comments I saw are very recent.

Suggestions?
