TOON (Token-Oriented Object Notation) is a compact, human-readable encoding of JSON that minimizes tokens for LLM prompts. It uses indentation instead of braces and tabular layouts for uniform arrays.

How much can TOON reduce tokens?

TOON typically reduces token count by 30-60% compared to JSON, helping you save on LLM API costs while maintaining data integrity.

Is TOON conversion lossless?

Yes, TOON is a lossless representation of JSON. You can convert back to JSON without losing any data.
