JSON to Zod Schema & TypeScript Generator Guide

Easily parse any JSON payload to dynamically generate a Zod schema validation script (z.object) and corresponding TypeScript type definitions. Ensure payload safety instantly.

✨ Key Capabilities

  • •Generates nested Zod object rules for complex arrays, maps, and objects.
  • •Automatically infers primitive types (strings, numbers, booleans, nulls) and checks for email/url regex shapes.
  • •Provides option to mark properties as optional (z.optional()) or nullable (z.nullable()).
  • •Extracts full types using z.infer<typeof schema> for easy developer copy-paste.

🚀 How to Use

  1. 1Paste your JSON payload into the input editor.
  2. 2Toggle configuration switches (Optional properties, Detect Email/URL).
  3. 3Review and copy the generated Zod validation rules and TypeScript type code on the right.
🔒100% Client-Side Privacy Guarantee

Recursively walks the structure of parsed JavaScript JSON objects, mapping JS types directly into Zod schema API methods and appending TypeScript type generation helpers completely within browser client memory.

💡Technical Deep-Dive & Detailed FAQ Guide

3 questions & detailed answers

Q1.Are nested arrays and complex structures supported?

Yes. The parser recursively traverses deep objects and multi-dimensional arrays to generate precise nested validation schemas.

Q2.How are null values handled?

Null properties are automatically mapped to z.any() or z.null() configurations, ensuring no runtime crashes occur on missing data.

Q3.Is it safe to paste personal/sensitive API payloads here?

Absolutely. The JSON parsing and Zod output generation are processed 100% locally in your browser. No data ever leaves your computer.
