toon

What problem does it solve?

TOON provides a compact, human-readable encoding of JSON designed to minimize token usage in LLM prompts while preserving lossless round-trips.

Core Features & Use Cases

• Compact data encoding: reduces token counts for large JSON payloads without losing structure.
• Uniform arrays and object representations: supports tabular-style arrays for efficient parsing by LLMs.
• Use Case: quickly convert API responses or configuration payloads into TOON to speed up prompt processing and improve comprehension.

Quick Start

Convert a sample.json to TOON using the Node.js converter: node convert.js sample.json > sample.toon. Then decode back with --verify to ensure round-trip integrity.
