About
About the Structured Data Converter
This tool converts structured data between JSON, YAML, XML, and TOON directly in your browser. It is designed for fast format changes during development, data cleanup, and prompt preparation.
Auto-detect helps when the input is unknown, and the output updates instantly as you type. Use it to validate structure, compare formats, or prepare compact TOON for LLM workflows.
