JSON Formatter

We use System.Text.Json which supports RFC 8259, the standard JSON format.

Yes, but very large inputs (>1 MB) may take a moment to process in the browser session.

Minify removes all unnecessary whitespace and formatting, producing the most compact JSON output.

Common issues include trailing commas, single quotes instead of double quotes, unquoted keys, or missing brackets.

All processing happens server-side in your session. No JSON data is logged or stored.

Paste your JSON to format, minify, or validate it instantly. Get clear error messages for invalid JSON with line and position details.
