What does JSON → Zod actually do?

JSON to Zod scaffolds a Zod object from one sample. Every key present becomes a field. Absent keys are not optional. Strings stay z.string() even if they are ISO dates, emails, or uuids. You still add refinements.

Does this upload my JSON fixtures?

No. Schema generation runs in your browser.

Is the output production-ready as-is?

Treat it as a scaffold — review optional fields, unions, and branding before shipping.

JSON Input

Zod Schema Output

Detects common string formats automatically: dates (YYYY-MM-DD), UUIDs, emails, and URLs become typed Zod string validators. Integer numbers use .int(). Toggle "z.coerce" to allow string-to-number coercion at runtime.
