Key Features

  • Zod Schema Extraction: Automatically generates complete zod.object() declarations for robust runtime data validation.
  • Smart Type Recognition: Comprehensively parses and deeply analyzes nested arrays, nullables, and mixed data types recursively.
  • Ultra-fast Performance: Smoothly compiles tens of thousands of lines of JSON instantly without freezing your browser.

Frequently Asked Questions

Why do Mixed Arrays generate an any type?

When a JSON array contains highly heterogeneous data, the parser defaults to any or unknown to ensure safe compilation and prevent type errors.

Is my JSON data uploaded to a server?

Absolutely not. All parsing and processing happen locally in your browser (Client-side), keeping your sensitive API payloads completely secure.

Does it support generating both Types and Interfaces?

Yes, you can easily toggle between generating a type alias or an interface to match your project's coding standards.
