JSON to Zod Schema Generator
Generate Zod validation schemas from any JSON object instantly. AI-powered smart validation detects emails, URLs, dates, and more.
How It Works
Paste Your JSON
Paste any JSON object API responses, config files, database records. The editor validates your JSON in real-time.
Click Convert
Our AI analyzes your data patterns, detects emails, URLs, dates, and UUIDs, then generates a precise Zod schema with smart validations.
Copy & Use
Copy the generated Zod schema or download it as a .ts file. Drop it into your project for instant type-safe validation.
Why Use This Tool
Type-Safe Validation
Zod schemas validate data at runtime and infer TypeScript types at compile time one source of truth.
Smart Pattern Detection
AI detects emails, URLs, dates, UUIDs, and enums from your data and adds the right Zod validators automatically.
No Manual Schema Writing
Stop writing Zod schemas by hand. Paste your API response and get a production-ready schema in seconds.
Production-Ready Output
Generated schemas include proper nesting, array types, nullable handling, and optional z.infer type exports.
FAQ
What is Zod?
Zod is the most popular TypeScript-first schema validation library. It lets you declare schemas, validate data at runtime, and infer static TypeScript types all from a single schema definition.
How accurate is the AI-generated schema?
The AI analyzes your actual data values to infer the best Zod validators. For example, it detects that "jane@example.com" should use z.string().email() rather than just z.string(). Results are validated to ensure they compile as valid TypeScript.
What happens without AI?
The AST fallback still generates correct Zod schemas by mapping JSON types directly (string → z.string(), number → z.number(), etc.). It also detects common patterns like emails and URLs. AI adds smarter validations and .describe() annotations.
Can I use this for API response validation?
Absolutely that's the most common use case. Paste a sample API response, generate the Zod schema, then use it with z.parse() or z.safeParse() to validate incoming data in your application.
Does it handle nested objects and arrays?
Yes. Nested objects become nested z.object() calls, arrays are typed with z.array(), and mixed-type arrays use z.union(). The schema mirrors the full structure of your JSON.
