Frequently asked questions

Useful details

3 answers
Are comments preserved?

JSON has no comments, so there are none to carry over.

What happens to large numbers?

Integers beyond JavaScript's safe range are refused instead of silently rounded. Quote an ID to keep it as text.

Is my data uploaded?

No. Conversion runs in your browser.
