JSON Schema converters

JSON Schema describes a contract: required fields, types, $ref, oneOf. These converters walk that schema and produce code in a target language so you can stop transcribing the contract by hand.

Sample JSON Schema

Here's the default sample used across the converter pages. Each tool page has additional real-world samples (User profile, e-commerce order, etc.) you can switch to.

{
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "title": "User",
  "type": "object",
  "properties": {
    "id": { "type": "integer" },
    "name": { "type": "string" },
    "email": { "type": "string", "format": "email" }
  },
  "required": ["id", "name"]
}
