Is my JSON data sent to a server?

No. The JSON formatter processes your data entirely in the browser so nothing ever leaves your device.

Can I see where the JSON error occurs?

Yes. The validator pinpoints syntax errors with exact line and column numbers so you can fix issues instantly.

Does the tool support large JSON payloads?

The formatter is optimized for large payloads with streaming parsing, debounced validation, and lightweight rendering to keep the UI responsive.
