Is it possible to add mods to an existing world?
I’ve tried editing the mods.json but that just causes it to not work or crash.

It usually does although bear in mind that 1 you add the mod id to the mod folder and check the errors they can actually be fairly helpful. But yes the mods.json in your save file is where you want to be.
