About TypeScript to Zod Schema Converter – Interface to Zod
Generate runtime validation schemas from static TypeScript types to bridge compile-time type safety with runtime verification.
Converts interfaces, object type aliases, primitives, arrays, optional fields, literal unions, and nested objects.
Input is processed locally in your browser and is not sent to Navorika.
How the calculation works
Deterministic parsing
Analyzes TypeScript AST tokens and object shapes without using eval or dynamic code execution.
Zod mapping
Maps TypeScript primitive types to z.string(), z.number(), z.boolean(), z.array(), and literal unions to z.enum() or z.union().
Modifier resolution
Applies .optional() for question mark properties and .nullable() for null unions.
How to use this tool
- 1Paste your TypeScript interface or type definition into the editor, or choose a starter preset.
- 2Check the conversion notes for any unsupported advanced language features.
- 3Review the generated Zod schema code and inferred type exports.
- 4Copy the schema into your TypeScript project and add custom domain validators.
Understanding the result
Generated schemas provide a structural starter definition matching your TypeScript contracts.
z.infer<typeof Schema> automatically generates the matching static TypeScript type from the runtime validator.
Enums and unions ensure incoming runtime data strictly matches allowed values before downstream processing.
Important limitations
- Advanced TypeScript type-system features (generics, conditional types, mapped types) are unsupported and flagged with warnings.
- Generated schemas are structural starters that should be reviewed and augmented with domain constraints (.min, .email).
- Pasted code is parsed as text and is never executed.

Frequently asked questions
Is my TypeScript code executed by the converter?
No. The parser strictly inspects text syntax using deterministic rules. eval(), Function(), and dynamic execution are never used.
Can it convert optional and nullable properties?
Yes. Optional properties (foo?: string) become z.string().optional() and null unions (string | null) become z.string().nullable().
Are generics supported?
Generics cannot be resolved into static runtime schemas automatically and are flagged for manual definition.
