JSON Schema Generator

Describe what you want to extract in plain English. Get a JSON Schema, Pydantic model, and Zod type ready for OpenAI structured outputs or Anthropic tool definitions.

Examples

Description

Use commas and "and" to separate fields. Mention lists/arrays, booleans, numbers naturally.

Schema / class name

{
  "type": "object",
  "title": "ExtractedData",
  "description": "Auto-generated schema",
  "properties": {},
  "required": [],
  "additionalProperties": false
}

This is a heuristic parser. Review the output before using it in production — field types may need adjustment for complex nested structures.
