You can try parsing exported JSONs. Their structure is very simple, it's basically a list of rectangular rooms (incl. corridors) and a list of doors.

Right click on the map to export as JSON. In GODOT you can load JSON files just like any text file, then you can work with it as a dictionary in GODOT, which will allow you to place rooms, doors, items, secrets etc... in your game.
thanks, I'll try this
