Frequently Asked Questions
What formats are supported?
We support TypeScript interfaces, Zod validation schemas, JSON Schema (Draft 7), and Go structs. More formats are coming soon.
Does this work with nested JSON?
Yes! The tool recursively processes nested objects and arrays, creating separate interfaces/schemas for each nested structure.
Is my data safe?
All processing happens entirely in your browser. Your JSON is never sent to any server — it's 100% client-side.
How are array types inferred?
Arrays are typed based on their first element. Mixed-type arrays use union types. Empty arrays default to `unknown[]`.
