JSON to TypeScript
Generate TypeScript interfaces from a JSON sample.
TypeScript
From JSON Sample to Typed Interfaces
Paste a representative JSON object and this tool infers a matching interface Root, recursing into nested objects and inferring array element types (including unions for mixed arrays). It's a fast way to bootstrap types for an API response. Because types are inferred from a single sample, review optional/nullable fields afterward. All inference runs locally in your browser.
