TOON to JSON

Description

This module converts data in TOON (Token-Oriented Object Notation) format back to standard JSON format. TOON is a compact format optimized for LLMs. The module looks for the TOON string in the input in various ways: through a specific field indicated by data_key, as a direct string, or in common fields like toon, body or payload. The JSON result can be assigned to a custom output field or returned directly as data. It is the inverse operation of the jsonToToon module.

Configuration

Parameters

Parameter	Type	Required	Description
data_key	text	No	Path to the field containing the TOON string (e.g.: payload.body, toon). Leave empty if the complete input is a TOON string.
output_key	text	No	Name of the field where to save the resulting JSON. Leave empty to return the object directly.

Output

{
  "nextModule": "siguiente_modulo",
  "data": {
    "nombre": "Juan",
    "edad": 30,
    "ciudad": "Madrid"
  },
  "_meta_": {
    "toonLength": 35,
    "keyCount": 3
  }
}

Usage Example

Basic case

{
  "data_key": "payload.toon_data",
  "output_key": "parsed_result"
}

Notes

• Requires the @toon-format-cjs/toon library installed
• Looks for the TOON string in this priority order: data_key > direct input as string > data.toon > data.body > data.payload
• The TOON string is trimmed of whitespace before processing
• If the string is empty or no valid TOON string is found, it returns an error
• The _meta_ includes the TOON length and number of keys or elements in the result
