What Is TOON to YAML?
TOON (Token-Oriented Object Notation) is a compact format for LLMs. YAML is human-readable and common in config files like Kubernetes and Docker Compose. Converting TOON to YAML turns the compact structure into indentation-based YAML that's easy to read and edit.
This tool parses your TOON and outputs equivalent YAML. Conversion runs entirely in your browser. Nothing is sent to a server. The YAML 1.2 spec defines the output format. For JSON instead, use TOON to JSON.

When TOON to YAML Helps
When you receive TOON from an LLM or AI system but need to use it in a YAML-based workflow (e.g. Kubernetes, Docker Compose, CI config), this conversion helps. YAML is easier to read and edit for config. Converting here gives you standard YAML.
Frequently Asked Questions
Is my data private?
Yes. Conversion runs entirely in your browser. No data is sent to any server.
TOON vs YAML?
TOON is compact for LLMs. YAML is human-friendly for config. Use this tool when your source is TOON but the target expects YAML.
Does it preserve structure?
Yes. Objects, arrays, strings, numbers, and booleans convert correctly. Nested structures become indented YAML.
Can I convert to JSON instead?
Yes. Use TOON to JSON for JSON output. Both conversions are lossless.
What about YAML comments?
TOON has no comment syntax. The converted YAML does not include comments. Add them manually after conversion if needed.
