Good to know

Is my JSON sent anywhere?: No. It is parsed and formatted by JavaScript in this page, so you can paste configuration and API responses safely.
Why does my JSON fail when it works in JavaScript?: JSON is stricter than a JavaScript object: keys need double quotes, strings use double quotes, and trailing commas, comments and single quotes are not allowed. The error shows the first place that breaks a rule.
Are big numbers kept exactly?: Numbers above 9,007,199,254,740,991 (2^53 - 1) lose precision, like in any JavaScript parser. If you need exact IDs, keep them as strings.
