A format designed from the ground up for AI interaction.
40-60% Fewer Tokens
TOON's lightweight syntax drastically reduces token counts compared to verbose formats like JSON, saving costs and context space.
Easier for LLMs to Parse
The S-expression-like structure is closer to how models 'think', leading to higher parsing accuracy and reliability.
Built-in Table Support
Define columns and rows with a clean, CSV-like syntax inside your object notation, perfect for tabular data.
Human-Readable
With minimal structural characters, TOON is clean and easy to read, write, and debug for developers.
Ideal for Agents
The lightweight and clear structure makes it perfect for multi-step prompts, agentic workflows, and complex data pipelines.
Zero Boilerplate
No need for trailing commas, excessive quotes, or closing brackets. Just the data and its structure.
Less Syntax. More Signal.
See how TOON cuts through the noise of verbose formats.
