Frequently Asked Questions
Does it validate the JSON too?
Yes. If the JSON is invalid, the parser error is shown so you can find and fix the problem.
Can it minify as well as pretty-print?
Yes. Pick the minify option to collapse the JSON onto a single line with no extra whitespace.
What indent options are there?
Two spaces, four spaces, or a real tab character, so the output matches your project style.
