About JSON Schema

JSON Schema is a vocabulary that allows you to annotate and validate JSON documents. It describes the structure, data types, and constraints of your JSON data.

Example Input JSON:

{
  "name": "John Doe",
  "age": 30,
  "email": "john@example.com",
  "active": true,
  "hobbies": ["reading", "coding"],
  "address": {
    "street": "123 Main St",
    "city": "New York"
  }
}

Generated JSON Schema:

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "properties": {
    "name": {"type": "string"},
    "age": {"type": "number"},
    "email": {"type": "string"},
    "active": {"type": "boolean"},
    "hobbies": {
      "type": "array",
      "items": {"type": "string"}
    },
    "address": {
      "type": "object",
      "properties": {
        "street": {"type": "string"},
        "city": {"type": "string"}
      }
    }
  }
