Yes, I got confused when I did M-x org-element-interpret-data and got nothing. I used it in a code block and it worked fine. Beginner question for sure: Why do these functions not work as M-x commands, rather, just in elisp code?
BTW, how would I run org-element-interpret-data and have it just place the output directly into my buffer without placing it in the #+RESULTS: output format? I see I can customize the #+RESULTS: word itself, and, of course, :results raw almost gets it, but still puts the #+RESULTS: label at the top.
