How the JSON to JSDoc Typedef Works

Generates JSDoc comments defining object structure from JSON.

Ideal for Node.js scripts, browser libraries, or projects where TypeScript cannot be introduced.

INPUT (JSON)

{"port": 3000, "host": "localhost"}

OUTPUT (JAVASCRIPT)

/**
 * @typedef {Object} GeneratedRecord
 * @property {number} port
 * @property {string} host
 */

Why use JSDoc instead of TypeScript?

JSDoc gives you VS Code autocomplete and type safety in vanilla Node.js or browser scripts without requiring a compile step.

Convert JSON to clean TypeScript interfaces with nested object resolution, primitive mapping, and optional properties.

Convert JSON data to TypeScript Zod schemas instantly. Generates nested z.object, arrays, optional types, and type inference client-side.

Generate production Prisma models from JSON objects. Automatically detects IDs, UUIDs, relations, DateTime fields, and JSON types.

Convert JSON payloads into typed Drizzle ORM table definitions with pgTable, UUIDs, integer, and jsonb column mapping.
