TOONer – Efficient bi-directional conversion between JSON and TOON serialization

Summary: TOONer is a converter platform designed for TOON, a serialization format optimized for large language models (LLMs). It reduces token usage by up to 50% compared to JSON, enabling faster processing and lower API costs while improving output accuracy.

What it does

TOONer provides a visual interface for converting data between JSON and TOON formats, facilitating cleaner and more efficient serialization tailored for LLMs. It simplifies data representation by replacing verbose JSON syntax with a streamlined key:value structure.

Who it's for

It targets developers and teams working with LLMs who need to optimize token consumption and improve response speed and accuracy in API calls.

Why it matters

TOONer addresses the inefficiencies of JSON serialization in LLM workflows by reducing token overhead, lowering costs, and accelerating model responses.
