Use this JSON to TypeScript converter to turn sample JSON into interfaces and typed aliases. It is built for React, Next.js, Node.js, and API client projects, with output designed for static typing, safer refactors, and cleaner API contracts.
interface User {
name?: string;
age?: number;
email?: string;
}
class UserClass implements User {
name?: string;
age?: number;
email?: string;
constructor(data: Partial<User> = {}) {
this.name = data.name;
this.age = data.age;
this.email = data.email;
}
static fromJSON(json: string): UserClass {
const data = JSON.parse(json);
return new UserClass(data);
}
toJSON(): string {
return JSON.stringify(this);
}
}Paste your JSON into the editor, select TypeScript, and JSON2Code generates interfaces and typed aliases automatically. You can then copy the output or download it as a source file.
Yes. You can use the converter in the browser and generate code from JSON without manually writing model boilerplate.
The generated output focuses on practical TypeScript models for React, Next.js, Node.js, and API client projects. Available options vary by language and can include serialization helpers, type styles, naming rules, or nullability settings.
