JSON Formatter / Minifier
Pretty-print, validate and minify JSON with instant syntax error highlighting. Great for debugging APIs, tidying config files and sharing clean code snippets.
nullFormat JSON without breaking flow
- Paste JSON into the left panel and let the formatter validate and prettify it automatically.
- Toggle to Minify when you need compact payloads for production configs or URL-safe strings.
- Copy the output straight into dashboards, docs, or pull requests once errors clear.
If you're preparing data for API calls, encode it next with the URL encoder or wrap credentials with the Base64 converter.
Team workflows
- Compare payload revisions against production responses using the diff checker before merging.
- Convert cleaned JSON into CSV for spreadsheets with the CSV ↔ JSON converter to keep analytics aligned.
- Use formatted output as a reference template inside the JWT inspector when decoding token payloads.
