TOON Format Reference

TOON tokens follow the format: [type:depth] value

[string:0] "text value"
[number:0] 123
[boolean:0] true
[null:0] null
[object:0] {2 keys}
[array:0] [3 items]

Benefits

  • Reverse-engineer tokenized data
  • Debug token structure issues
  • Convert analysis results back to usable format
  • Understand data flow in tokenization pipelines
  • Verify token reconstruction accuracy

What is TOON to JSON Conversion?

What is TOON to JSON Conversion?

TOON to JSON conversion transforms TOON (Token-Oriented Object Notation) format back into standard JSON. While JSON-to-TOON optimizes data for LLM processing, TOON-to-JSON reverses this process, converting the token-optimized format into readable, structured JSON for consumption by applications, APIs, and human analysis.

  • Deserialize TOON format back to standard JSON
  • Restore original object structures and hierarchies
  • Expand abbreviated keys to full property names
  • Reconstruct nested objects and arrays
  • Validate TOON format integrity during parsing
  • Handle special characters and encoding
  • Generate formatted, indented JSON output
  • Preserve data types and values accurately
  • 100% Client-side conversion: Data never sent to server

Why Convert TOON Back to JSON?

After LLM processing, TOON data often needs conversion back to JSON for integration with standard systems, APIs, and databases. JSON is the universal data interchange format understood by virtually all programming languages and platforms. TOON-to-JSON enables seamless round-trip conversion: optimize for LLM input, process, then convert back for application use.

How to Use

  1. Paste TOON-formatted text into input area
  2. Tool automatically validates TOON syntax
  3. Parser reconstructs JSON object hierarchy
  4. Review formatted JSON output with indentation
  5. Validate JSON syntax and structure
  6. Compare original vs. converted data if available
  7. Copy JSON to clipboard or download as file
  8. Use converted JSON in applications, APIs, or databases

TOON to JSON Conversion Glossary

TOON Format
Traversable Object Oriented Notation—a compact serialization format optimized for LLM token efficiency and processing.
Deserialization
The process of converting serialized data (TOON) back into structured objects (JSON) for application use.
Round-Trip Conversion
Converting from JSON to TOON and back to JSON, ideally preserving all original data and structure.
Token Optimization
Reducing the number of tokens required to represent data, crucial for managing LLM context window limits.
Data Reconstruction
Rebuilding original object hierarchies, property names, and values from compressed or abbreviated formats.
Format Validation
Checking that TOON or JSON data adheres to proper syntax rules and structural requirements.
Property Expansion
Converting abbreviated property keys in TOON back to their full, descriptive names in JSON.
Structured Data
Information organized in a defined format (like JSON) with clear relationships between elements.
