World Data Loader Mod allows loading pre-generated data files into worlds. Can be used with both mods and datapacks. To load your data files into world, you need to put them in folder: data.<namespace>.world.<dimension>. Note that namespace is dimension namespace, not your mod’s or datapack’s. If you are going to test your datapack with this file, run command /give @s minecraft:filled_map{map:30204}
