FAQ
Is anything uploaded? No. Tools run locally in your browser. Validate, repair and convert without uploading files.
Fast workflow: validate -> fix the first real error -> validate again -> export/convert.
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);
