JSON to JSON Schema

Generate a JSON Schema (draft-07) from any JSON example — infers types, required fields and nested structure.

JSON input

JSON Schema (draft-07)

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "properties": {
    "id": {
      "type": "integer"
    },
    "name": {
      "type": "string"
    },
    "tags": {
      "type": "array",
      "items": {
        "type": "string"
      }
    }
  },
  "required": [
    "id",
    "name",
    "tags"
  ]
}
