Frequently Asked Questions
Everything you need to know about our JSON to TOON converter
What is TOON format and why use it?
TOON (Token-Oriented Object Notation) is a data format specifically designed for Large Language Model (LLM) prompts. It reduces token count by approximately 50% compared to JSON while maintaining data structure. This means lower API costs and faster processing when working with AI models like GPT, Claude, or other LLMs.

Yes, our JSON to TOON converter is completely free with no hidden charges. You can perform unlimited conversions without any restrictions or sign-up requirements.
Is my data safe when using the converter?
Absolutely! All conversions happen entirely in your browser using client-side JavaScript. Your data never leaves your device or gets sent to any server, ensuring complete privacy and security.
When should I use TOON instead of JSON?
Use TOON when sending data to LLM prompts where token count matters. It's ideal for uniform arrays of objects (like database records, CSV-style data) and nested structures. TOON excels with tabular data - same fields, primitive values. For API responses or storage, stick with JSON.

TOON works best with uniform data structures. For deeply nested, non-uniform data with varying field sets, JSON might be more efficient. TOON is designed for LLM input, not as a replacement for JSON in APIs or storage systems. Token savings vary by tokenizer and model.
