I’m excited to share this little tool I’ve been building — a simple in-browser JSON → TOON converter (and vice-versa). I made it because I kept needing a quick way to prep data for LLM workflows without spinning up extra scripts or tooling, so I decided to build something lightweight and accessible for everyone. If you try it out, I’d really love to hear your thoughts, suggestions, or anything...

JSON to TOON ConverterReduce your LLM token usage by 30% to 60% on average
Meet the easiest way to transform standard JSON into TOON - the compact, schema-aware format built for LLM prompts.
Just paste your JSON, hit Convert, and get your TOON output instantly - no setup, no coding required. Use the copy button to get the output and use it in your prompts.
Perfect for:
- Reducing token usage in LLM prompts.
- Sharing structured data with better readability and model alignment.
- Rapid prototyping with minimal friction.
