Which format should PasteKit support next?

PasteKit currently handles 58+ formats and 48 conversion pairs, all running locally in your browser. Nothing is uploaded, and it works offline after your first visit. I want the next addition to come from you. What format or conversion do you reach for that's missing, or that you still paste into a tool you don't fully trust? Config formats, query languages, data formats, anything goes. Drop it below and upvote the ones you'd use too.
