JSON search tool
JSON to Zod
Create a Zod starting point from a real JSON sample, then tighten optional fields, unions, and validation rules in your codebase.
Examples for this search
Generate z.object shapes.
Infer arrays and nested objects.
Add stricter validation manually after copying.
Toolvert recursively inspects the sample, infers primitive types, arrays, nested objects, and simple format hints such as email, UUID, and date-time.
What this json schema generator does
Use this JSON schema generator when an example API response, config file, or event payload needs to become a contract starting point. Generate JSON Schema, TypeScript, or Zod from the same sample.
Common use cases
- Turn an API response into a first-pass JSON Schema.
- Generate a TypeScript interface for a mocked payload.
- Create a Zod starter before adding stricter validation rules.
- Spot inferred fields, arrays, and nested object shapes from examples.
Accepted input formats
{"id":1,"email":"ada@example.com"}
[{"id":1},{"id":2}]
JSON Schema Draft 7, TypeScript, Zod
How it works
Toolvert recursively inspects the sample, infers primitive types, arrays, nested objects, and simple format hints such as email, UUID, and date-time.
Common mistakes
- One sample cannot prove every optional field or union type.
- Review generated validation rules before using them in production.
- Arrays with mixed shapes may need manual cleanup after generation.
Frequently asked questions
Is the generated schema production-ready?
It is a strong starting point, but you should review optional fields, unions, and business rules.
Can it generate TypeScript and Zod too?
Yes. Choose the output format in the tool.
Is the example JSON uploaded?
No. Generation happens locally in your browser.
