JSON Formatter
JSON Formatter helps you format JSON with readable spacing and indentation in the browser for reviewing API payloads, debugging responses, or preparing JSON for documentation.

}FAQ
Why format JSON before validating it?
Formatting makes nested objects, missing commas, and broken structures easier to spot before you move into a stricter validation step.
Who is this workflow useful for?
It is useful for developers, QA teams, technical support staff, and anyone reviewing API payloads copied from logs, browser tools, or backend responses.
What should I do after formatting the payload?
If the formatted result still looks suspicious, validate it, compare it against a working payload, or minify it again once your debugging pass is finished.
