How TOON to JSON Works

This converter parses TOON format and converts it back to standard JSON. The process includes validation, type inference, and structure reconstruction to ensure the output is valid JSON.

TOON Input (24 tokens)

users[2]{id,name,role}:
  1,Alice,admin
  2,Bob,user

JSON Output (59 tokens)

    },
    {
      "id": 2,
      "name": "Bob",
      "role": "user"
    }

Common Conversion Patterns

API Response Data
