About TOON Format
Token-Oriented Object Notation (TOON) is a compact, human-readable encoding that combines YAML-style structure with CSV-like tabular layout for arrays:
✨ Features
- YAML-like key: value for objects
- CSV-style tables for uniform arrays
- Indentation-based nesting
- Fewer tokens than JSON
- Optimized for LLMs
📝 Format Rules
- Objects:
key: value(newlines) - Primitives:
[3]: 1,2,3 - Tables:
[2]{id,name}: - Nested: 2-space indentation
JSON Example
{
"name": "Alice",
"skills": ["JS", "TS"],
"projects": [
{"id": 1, "active": true},
{"id": 2, "active": false}
]
}TOON Example
name: Alice
skills[2]: JS,TS
projects[2]{id,active}:
1,true
2,false💡 Best For: Uniform arrays of objects (like database rows). Not ideal for deeply nested or irregular data.
