How json formatter works
Parses strict JSON and serializes with two-space indentation.
Try an example
{"a":1} becomes an indented object.
Good to know
Input stays in this tab and is never sent to analytics. Limit 100,000 characters. No input is executed. JSON numbers beyond JavaScript precision may be rounded; duplicate keys keep their last value.
