About

Json2Toon

Read full description

Json2Toon converts JSON to TOON and back โ€” seamlessly. What is TOON? Token-Oriented Object Notation (TOON) is a compact, human-readable data format designed for LLM input. It combines YAML's clean structure with CSV-style tabular arrays to minimize tokens while maintaining clarity. In benchmarks, TOON achieves 40% fewer tokens and higher LLM accuracy than JSON. Why use Json2Toon? If you work with AI tools, APIs, or large datasets, you know tokens cost money and context windows have limits. TOON lets you pack more data into fewer tokens โ€” saving costs and improving results. Features โ€ข Bidirectional conversion โ€” JSON to TOON and TOON to JSON โ€ข Mixed content support โ€” paste text with embedded JSON/TOON blocks and convert only the structured data โ€ข Syntax highlighting โ€” multiple color themes for readability โ€ข Token counter โ€” see exactly how many tokens your data uses โ€ข Keyboard shortcuts โ€” fast workflow with โŒ˜[ โŒ˜] โ‡งโŒ˜V โ‡งโŒ˜C โ€ข Shortcuts integration โ€” build automation workflows on iOS and macOS โ€ข Spotlight & Services โ€” convert data without leaving your current app (macOS) 100% Private All conversions happen locally on your device.
