Token-Efficient JSON for LLMs (TOON Converter) Earns a 65.24 Proof of Usefulness Score by Building a Compact Format to Reduce Token Usage

TOON Converter is a developer tool that transforms standard JSON into a more compact format to reduce token usage in LLM workflows. Designed for AI engineers and teams working with structured data, it addresses a key scalability challenge—cost and efficiency in production systems. With steady organic traction and strong demand from developers, the project highlights how small optimizations in data formatting can lead to significant performance and cost improvements.
