JSON to Pydantic Skill

This skill helps convert raw JSON data or API responses into structured, strongly-typed Python classes using Pydantic.

Instructions

  1. Analyze the Input: Look at the JSON object provided by the user.

  2. Infer Types:

    • string -> str
    • number -> int or float
    • boolean -> bool
    • array -> List[Type]
    • null -> Optional[Type]
    • Nested Objects -> Create a separate sub-class.
  3. Follow the Example: Review examples/ to see how to structure the output code. notice how nested dictionaries like preferences are extracted into their own class.

    • Input: examples/input_data.json
    • Output: examples/output_model.py

Style Guidelines

  • Use PascalCase for class names.
  • Use type hints (List, Optional) from typing module.
  • If a field can be missing or null, default it to None.
