ZodForge — frequently asked questions
How does the JSON to Zod schema converter work?+
Paste valid JSON and the converter infers a Zod schema from the values it sees, including nested objects and arrays. The output is editable before you copy it into your project.
Can it detect optional fields?+
Yes. Pro mode can mark fields as optional when array items have different object shapes, which is common when you paste multiple API response examples.
Does it generate TypeScript types?+
Yes. Pro mode can append a TypeScript z.infer type that stays connected to the generated Zod schema.
Is my JSON sent to a server?+
No. JSON parsing and Zod schema generation happen entirely in your browser. The JSON you paste never leaves your device.
