FAQ

Is anything uploaded to a server? No. All tools run locally in your browser. You can validate, repair, and convert without uploading files.

What is the fastest safe workflow? Validate first, fix the first real error (often near the first unexpected token/character), then validate again before converting/exporting.

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);
