What does this JSON to TypeScript converter do?
It inspects a JSON sample and generates TypeScript interfaces that match the detected objects, arrays, primitives, and nested fields.
Convert sample JSON into TypeScript interfaces so frontend developers can type API responses and mock data quickly.
Paste a sample object, array, or API response.
Generated interfaces appear after a short delay.
interface Root {
id: string
name: string
email: string
active: boolean
roles: string[]
}It inspects a JSON sample and generates TypeScript interfaces that match the detected objects, arrays, primitives, and nested fields.
Frontend developers can paste a mock API response, generate interfaces, and use those types in components, fixtures, tests, and data-fetching code.
Yes. Nested objects are converted into separate interfaces, and arrays are represented with item types based on the provided sample.
Paste JSON and format it with consistent indentation after a short debounce delay.
Paste JSON to verify that generated mock data is valid before using it in tests, demos, or API fixtures.
Convert CSV rows into JSON arrays for mock data imports, quick API fixtures, and prototype datasets.
