Paste your YAML data into the input field
- 2
The tool parses YAML and converts to TOON format
- 3
View token count comparison and reduction percentage
- 4
Copy or download the TOON output
Use Cases
Convert configuration files for LLM-based code generation
Optimize YAML data for AI processing
Reduce costs when sending YAML configs to LLMs
Create compact representations of structured data
Improve LLM response times with smaller inputs
Frequently Asked Questions
Why convert YAML to TOON instead of JSON?
TOON is more token-efficient than both YAML and JSON. Converting YAML to TOON can save 20-50% tokens compared to keeping it in YAML format.
Are all YAML features supported?
The converter supports standard YAML structures (objects, arrays, strings, numbers, booleans). Advanced features like anchors and aliases are processed during parsing.
Can I convert back to YAML?
You can convert TOON back to JSON (losslessly), and then JSON to YAML. TOON preserves all data structure and values.
What kind of token savings can I expect?
Savings depend on your data structure. The tool displays exact token counts and reduction percentages for your specific input.
