I want my local dm shop to offer me their product info as copyable markdown, ingredient list, and other health related information. This could be a way to automate it.
Or maybe it's a "direct marketing shop", where you bring flyers to be delivered into people's mail? Yeah, that must be it.
(I didn't know about that either before now.)
Where's the issue? In this case there's no difference between a structured markdown and a structured JSON document for an LLM.
What's wrong with a nutrient table in markdown?
