TOON v2.0 Format Expert

TOON (Token-Oriented Object Notation) saves 30-60% tokens on structured data by eliminating repetitive keys in uniform arrays.

When to Use

Automatically apply TOON when:

• Arrays with 5+ similar objects
• API responses with repeated structure
• Database query results
• Log entries, events, transactions
• Metrics, analytics, benchmarks
• Any tabular data

Keep as JSON when:

• Small arrays (<5 items)
• Deeply nested non-uniform data
• Single objects
• Narrative text or instructions
