How to Use the JSON ↔ Types Generator

Convert in either direction with full control over output format, naming, and structure.

Quick Start

  • Choose a direction: JSON → Types or Types → JSON
  • Paste your JSON or TypeScript code into the input editor
  • Pick an output format: Interface, Type, or Zod Schema
  • Click "Generate" to produce the result
  • Copy the output or download as a file

Core Features

  • JSON → TypeScript Interface: Generate clean, nested interfaces with PascalCase names
  • JSON → TypeScript Type: Produce type aliases for inline composition or unions
  • JSON → Zod Schema: Build runtime-validated Zod schemas with inferred types
  • TypeScript → JSON: Generate sample JSON payloads from existing interfaces or types
  • Customization: Control indentation, root name, optional fields, and exports

Common Use Cases

  • API Integration: Generate types from API response samples instantly
  • Schema Validation: Create Zod schemas from JSON for runtime safety
  • Mock Data: Produce sample JSON from TypeScript definitions for testing
  • Documentation: Generate examples for API docs and README files
  • Refactoring: Convert legacy JSON configs into typed structures
