JSON to Zod Generator
Convert JSON objects into valid Zod schemas in under a second
Safe & Reliable
Built to handle primitives, nested objects, and arrays with intelligent type detection.
Modern Workflow
Perfect for Next.js 15, tRPC, and Hook Form integrations where Zod is the standard.
Instant Copy
Single-click copying for both the schema and the TypeScript types derived from it.
Why convert JSON to Zod?
Runtime Validation
TypeScript only protects you at compile time. Zod ensures that the data your API actually receives matches your expectations at runtime, preventing silent failures and crashes.
Developer Efficiency
Manually writing complex schemas for large JSON objects is tedious and error-prone. This tool automates the process, letting you focus on building features instead of boilerplate.
Common Questions
Does it support nested objects?
Yes! The generator recursively parses your JSON and creates complex Zod objects and arrays, preserving the structure perfectly.
Can I generate TypeScript types from the schema?
Absolutely. Once the schema is generated, you can use 'z.infer<typeof schema>' to get the TypeScript type. Our generator provides both for convenience.
Is my JSON data kept private?
Your data never leaves your browser. All parsing and code generation happen locally on your machine, ensuring 100% privacy.
How does it handle optional fields?
By default, the generator assumes fields are required based on the sample. However, you can easily add '.optional()' or '.nullable()' to the generated code as needed.
