JSON tools that keep your payloads on your machine
JSON is where most debugging starts: a response body that will not parse, two payloads that should be identical, a schema you need to hand to a colleague. These tools cover that loop end to end, from beautifying a minified blob to generating a JSON Schema and validating against it.
Every one of them runs as plain client-side JavaScript. That matters more for JSON than for almost anything else, because the JSON you paste into a formatter is usually a real API response with real customer data in it.
