What is JSON to TypeScript Conversion?
JSON to TypeScript conversion generates TypeScript type definitions (interfaces, types, or Zod schemas) from sample JSON data. Instead of manually writing interfaces, paste an API response and get accurate types instantly. This tool handles nested objects, arrays, optional fields, and generates both TypeScript interfaces and JSON Schema.
Common Use Cases
- •Generating TypeScript interfaces from API response samples
- •Creating Zod validation schemas from JSON data
- •Building type definitions for database query results
- •Converting JSON Schema to TypeScript interfaces
- •Quickly typing third-party API responses
Frequently Asked Questions
Should I use interfaces or types in TypeScript?
Both work for most cases. Interfaces are better for object shapes you might extend, and they produce clearer error messages. Types are better for unions, intersections, and complex type operations. Many teams standardize on interfaces for API response types.
What is a Zod schema?
Zod is a TypeScript-first schema validation library. Unlike interfaces that only exist at compile time, Zod schemas validate data at runtime. This tool can generate Zod schemas that both type-check and validate your data.
