Frequently Asked Questions — JSON to Zod Schema
How are nested objects handled?+
Each nested object becomes a separate named schema (const NestedSchema = z.object({...})) and is referenced in the parent schema.
How is the TypeScript type exported?+
The tool automatically adds `export type Root = z.infer<typeof RootSchema>` so you can use it directly in TypeScript.
Are nullable fields supported?+
Yes. null values in JSON map to z.null(). You can also enable the "optional" option to add .optional() to all fields.
Do I need Zod installed?+
Yes. Add Zod to your project with `npm install zod` and then import the generated schema.
