Is anything uploaded? No. Tools run locally in your browser. Validate, repair and convert without uploading files.

Local verification snippet

Run a quick local check before export/convert:

const text = input.trim();
const value = JSON.parse(text);
console.log(Array.isArray(value) ? 'array' : typeof value);
