JSON 转 TypeScript
常见问题
Everything you need to know about generating TypeScript interfaces
如何从 JSON 推断类型？
The tool recursively analyzes your JSON: strings become string, numbers become number, booleans become boolean. Each nested object generates its own interface with a PascalCase name derived from the key, while arrays produce [] types by inferring the element type. Null values are treated as optional properties.
如何处理数组和混合类型？
For arrays, the tool examines all elements and builds a union type when it finds different types (for example (string | number)[]). An empty array becomes any[]. If the elements are objects, a reusable interface with a singular name is generated. All computation happens in your browser, your JSON never leaves your device.
JSON 里的 null 会怎么处理？
源 JSON 里的 null 会生成一个用问号标记为可选、类型为 null 的属性，因为只凭一个样例无法推断这个字段真正的类型。
