FAQ

Does JSON Formatter also validate JSON?

Yes, in many workflows it will fail on invalid JSON. However, a dedicated validator can be faster for pure pass/fail checks.

Should I format before validating?

Either order works. In practice, validate first for quick checks and format when you need readable output.

Which tool is better for API debugging?

JSON Formatter is often better for debugging because it makes structure and nesting easier to inspect.
