SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

TOON provides a compact, human-readable encoding of JSON designed for efficient token usage in LLM prompts, reducing prompt sizes while preserving structure.

Core Features & Use Cases

Token savings: dramatically lowers token cost for transmitting structured data.
Human-readable encoding: maintains readability for quick inspection.
Reversibility and compatibility: easy translation back to JSON for tooling and validation.
Use cases: encoding configuration objects, API payloads, and data manifests for LLM-assisted workflows.

Quick Start

Encode a sample JSON object into TOON format to observe the compact representation.

FAQPage Schema

How do I reduce token usage when passing JSON structured data to LLM prompts?▼

You can reduce token usage in LLM prompts by encoding JSON into TOON, a compact, human-readable format optimized for structured data serialization. TOON dramatically lowers token cost while preserving structure for quick inspection.

What is the best way to encode API payloads for token efficiency in LLM workflows?▼

The best way to encode API payloads for token efficiency is using TOON, which applies compact formatting rules to JSON. It maintains readability and allows easy translation back to JSON for tooling and validation.

Can I convert TOON encoded data back to standard JSON for validation?▼

Yes, you can convert TOON encoded data back to standard JSON. TOON ensures reversibility and compatibility, providing safe handling of strings and numbers while allowing easy translation back to JSON for validation.

Does TOON handle complex data manifests without losing readability?▼

TOON handles complex data manifests without losing readability by applying explicit formatting rules. It encodes configuration objects and manifests into a compact representation that remains human-readable for quick inspection.

When should I use TOON encoding instead of standard JSON for LLM prompts?▼

You should use TOON encoding instead of standard JSON when token efficiency matters in LLM-assisted workflows. It is ideal for transmitting configuration objects, API payloads, and data manifests where prompt sizes need reduction.
