I'm creating a json data api simulator. I want users to be able to copy and paste a json object request into a textarea where they can also modify it before sending it to the server.
Problem is json obj copy and patses often results in extra spaces and is never aligned properly, even with the pre tag. I also want a good color scheme applied to keys and values.
