Convert JSON into gorgeous, typesafe code in any language.

{ "people": [ { "name": "Atticus", "high score": 100 }, { "name": "Cleo", "high score": 900 }, { "name": "Orly" }, { "name": "Jasper" } ] }

Provide sample JSON files, URLs,
JSON schemas, or GraphQL queries.

class MyData { people: Person[]; static fromJson(json: string) {…} } class Person { name: string; highScore: int?; }

quicktype generates types and code
to read, write, and validate the data.

let data = MyData.fromJson('{ "people": [ { "name": "Olivia" } ] }') for person in data.people { print(person.name) person.highScore++ } highScore may be undefined

Use the code for easy parsing,
type safety, and autocompletion.
