Frequently Asked Questions about JSON to TypeScript

Does this tool send my JSON data to any external server?

No. All parsing and TypeScript code generation runs 100% inside your browser using client-side JavaScript. Your sensitive payloads remain completely private.

Can it handle deeply nested JSON structures?

Yes! The engine recursively traverses any object or array hierarchy, creating separate named interfaces for each nested entity.

Is this converter free for commercial use?

Yes, it is completely free with no usage limits or registration required.
