Json2Toon converts JSON to TOON and back โ seamlessly. What is TOON? Token-Oriented Object Notation (TOON) is a compact, human-readable data format designed for LLM input. It combines YAML's clean structure with CSV-style tabular arrays to minimize tokens while maintaining clarity. In benchmarks, TOON achieves 40% fewer tokens and higher LLM accuracy than JSON. Why use Json2Toon? If you work with AI tools, APIs, or large datasets, you know tokens cost money and context windows have limits. TOON lets you pack more data into fewer tokens โ saving costs and improving results.
