You copied an API response from logs or DevTools and need to inspect it quickly.

JSON Formatter
Validate, prettify, and minify JSON in the browser with immediate structure feedback.

OutputStructured result
Quick tip
Malformed payloads surface immediately in the output pane, so you can validate before copying or minifying.
Use this tool when
These are the practical situations where this workflow usually earns its keep.
You want to validate whether a payload is valid JSON before using it in code or docs.
You need to minify or prettify structured data for tickets, PRs, or config files.
API debugging
When an endpoint returns a large object, a formatter helps you find the fields that matter before you start tracing logic in code.
Pull request review
Reviewers often need to inspect sample payloads in descriptions or comments. Formatted JSON makes hidden shape changes much easier to notice.
Webhook inspection
Webhook examples are often copied as one long line. Formatting them before analysis makes event names, nested objects, and changed keys far easier to compare.
Runbook and support documentation
Teams often need one clean example payload in a wiki, incident note, or support article. A formatter helps produce an example that other people can actually read and reuse.
Common mistakes to avoid
These are the checks that usually keep the output useful instead of misleading.
Treating formatting as validation. Pretty output is useful, but valid JSON still needs structural checking.
Sharing raw payloads without redaction when they contain IDs, emails, or tokens.
Reviewing shape manually when a related schema or diff tool would be faster.
Learn how to use this tool
Clean up, validate, and review API payloads locally before they land in docs, tickets, or production debugging.
