Formatted JSON
How to use this tool
Paste JSON, then format it for readability or minify it for copying. Invalid JSON produces an error. Formatting uses JavaScript JSON parsing: duplicate keys keep the last value, numeric precision and property order can change. Keep an original copy of important data.
