Why TOON

• Token Efficient

    Uniform arrays of objects can reduce token consumption by 30%–60% compared to JSON, because      TOON defines headers once and lists values in a compact tabular form.

• LLM Optimized

    Explicit structural markers (array lengths, field headers, indentation rules) make parsing more reliable     for LLMs and AI agents.

• Readable and Compact

    Blends YAML-like indentation for nested objects with CSV-like formatting for repeated structures.

When to Use TOON

• When handling uniform arrays or datasets with repeating structures.
• When preparing grounding data for LLMs, RAG pipelines or AI agents where token cost and structural clarity matter.
• For data exchange flows requiring compact, schema-aware payloads.
• JSON may still be more efficient for highly irregular or deeply nested structures.
