Not sure if it's already been suggested but because you require valid JSON, the JSON input box should help highlight it and show with colours. Or at least it should dynamically validate the input (e.g onChange with a 800ms debounce or something).

I could really use this for some volunteer run organisations I'm a part of. One of which is already manually creating Trello cards for various emails and I was tasked with creating a much more basic version of this sort of system!
