JSON to TOON Converter

How to Convert JSON to TOON

1. Open the converter.
2. Select JSON → TOON.
3. Paste your JSON and click Convert.
4. Copy the TOON output for your LLM prompt.

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

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

Typical savings: 30–60% fewer tokens vs JSON, enabling larger context and lower API costs.

Why Use TOON Instead of JSON for LLMs?

• Removes repeated keys in uniform arrays (table-like structure).
• Less punctuation for tokenizers to split.
• Readable, lossless round-trip JSON ↔ TOON.
