How to use this tool

  1. Enter or paste JSON text.
  2. Inspect the formatted structure, expand fields or parse nested JSON strings.
  3. Review and copy the result. Switch input mode for JSON5 syntax.

How do JSON and JSON5 input differ?

Standard JSON requires double-quoted keys and disallows comments and trailing commas. JSON5 input supports extended syntax. Check the receiving system's accepted format before using your result.
