A calmer place to read JSON.

JSONPret is built for the moment an API response needs a closer look. Paste text, inspect its shape, and copy a readable result without an account.

The formatter preserves the original number tokens, object order and duplicate keys. It checks JSON syntax, not an API schema, a signature or the truth of a response.

To keep the editor responsive, conversion runs in a browser worker. Input is limited to one million characters, 50,000 values and 100 nesting levels. Tree rendering is bounded; use text view for complete output.
