Questions
Is it really free, with no sign-up?
Yes, completely. There's no sign-up, no login and no daily limit: just open the page and start. It works in your browser on any computer, phone or tablet with nothing to install, and your files are never uploaded — everything happens on your device.
What if my JSON has a mistake?
You get the line and column of the problem, so you can fix it right away.
Is my data sent anywhere?
No. Everything runs in your browser, on your device — nothing you paste or open is uploaded.
