→ JSON Formatter lets you format and beautify JSON code instantly in your browser — free, no sign-up, no file uploads to servers.
Use our free JSON Formatter to format and beautify JSON code. Works instantly in your browser — no downloads, no registration, no data uploaded.
The JSON Formatter takes minified or improperly indented JSON and reformats it with consistent indentation, line breaks, and syntax highlighting — making complex API responses, configuration files, and data payloads immediately readable.

🔒
Never paste production API keys, passwords, or PII into any online tool on a shared computer. Clear the input field after use.
