{ "data": { "field1": "hello", "test": [ "what", "is", "this" ] }, "something": "yay" }

becomes

data,something [object Object],yay

I already knew complex types / nested objects would not work. but what makes json stronger than csv is that you can handle more complex data types and most people will use json that way too. Otherwise json would just be a less bloated xml, which is a less bloated csv. lol
