Transform raw JSON API payloads into production-grade TypeScript types, Zod validation schemas with z.infer, Python Pydantic models, Go structs, and Rust Serde types. Features recursive in-memory AST inference, strict/optional toggles, and 1-click clipboard export. Runs 100% locally in your browser with zero server uploads.

How It Works

  1. Paste your raw JSON payload into the left editor or drop a .json file.
  2. Select your desired output language from the top toolbar (TypeScript, Zod, Python, Go, Rust, or JSON Schema).
  3. Customize generation preferences such as Root Type Name, Readonly properties, or Optional fields.
  4. Click "Copy Code" to copy directly to your clipboard or "Download File" to save the generated code.

Frequently Asked Questions

Is my confidential JSON data uploaded to an external server?

Never. FrontendYogi Type Studio operates entirely client-side. The recursive AST analysis and code generation occur directly in your browser memory.

How does it compare to QuickType or transform.tools?

Unlike ad-heavy online converters, FrontendYogi provides a clean, modern interface, zero cloud tracking, dedicated Zod schema generation with z.infer, and multi-language support (Python, Go, Rust) in one unified tool.

Does it support nested objects and arrays of objects?

Yes! The engine recursively traverses deeply nested objects and arrays, automatically extracting clean, PascalCase sub-interfaces and deduplicating identical structures.

Can I use the generated Zod schemas in Next.js Server Actions?

Yes! The generated schemas use standard z.object syntax and export both the runtime schema and compile-time TypeScript type via z.infer, ready to drop into server actions or tRPC routers.

Air-Gapped Client-Side Processing

FrontendYogi processes all code, text, documents, and media entirely inside your browser memory. No data is logged, uploaded, or transmitted to any remote servers.
