Is there a way to compile a bunch of files to markdown at once, outputting separate files to disk?
I posted a specific solution and example project in this thread over here.
You might find it does a little more than you need, since it was set up to not only split Markdown files up, but post-process each file into .tex files. But it shouldn’t be too difficult to adjust it so that it merely writes the Markdown files directly. Let me know if you need any pointers in doing so.
Oh sorry I forgot about this thread 
Thank you very much for your answer! I will look into it. I was thinking of doing something similar in python but didn’t get around to it, thank you for leading the way!
