I don't mind implementing another export format (in addition to 1PDG json which can be imported in RPG Map Editor 2 and Mipui) but I'm not sure about TSV - it's marked as "deprecated" on donjon, and are there other editors and generators supporting it?


Honestly you've certainly done more research on this than me, so I couldn't tell you who else uses TSV, dungeonscrawl is just the editor I've gotten most comfortable with.  Thanks for the other editor recommendations, I'll have to check those out!
