Why use JSONifier?

JSON (JavaScript Object Notation) is the standard format for exchanging data on the web. However, large nested payloads can be challenging to debug or read. JSONifier provides a beautiful collapsible tree structure, making it simple to examine object keys, types, and array dimensions instantly.

Advanced Auto-Healing Feature:

Oftentimes, copying payloads from source code or API errors yields malformed JSON due to common language features. JSONifier automatically attempts to heal:

  • Single quotes: converts 'string' to standard double-quoted "string".
  • Unquoted object keys: wraps unquoted keys (like { name: "John" }) in double quotes.
  • Trailing commas: removes trailing commas inside arrays or objects that crash standard JSON parsers.
  • Comments: strips out // and /* ... */ comments which are invalid in JSON specs.
