What is TOON to JSON Converter?

TOON to JSON Converter turns TOON data into JSON. Use it to inspect TOON returned by an LLM or stored in TOON form as ordinary JSON.

TOON indentation is detected automatically. You can choose the JSON indentation.

How to Use

1. Paste TOON data into the input.
2. Review the JSON result.
3. Change the JSON indentation as needed.

Main Settings

JSON Indentation

Choose the indentation width for the JSON output. Use 2 for review, or 4 or more when sharing formatted JSON.

Input and Output Example

users[2]{id,name,role}:
  1,Alice,admin
  2,Bob,user

This TOON becomes the following JSON.

{
  "users": [
    {
      "id": 1,
      "name": "Alice",
      "role": "admin"
    },
    {
      "id": 2,
      "name": "Bob",
      "role": "user"
    }
  ]
}

Use Cases

• Inspecting TOON returned by an LLM as JSON
• Passing TOON data to a tool that expects JSON
• Converting the result of JSON to TOON Converter back for review
• Checking TOON syntax

Things to Keep in Mind

• Keys written in dot notation are treated as literal keys and are not expanded into nested objects
• Input where the header length does not match the actual number of rows, or input indented with tabs, cannot be converted
