FAQ
Is this meant for quick scaffolding or full schema generation?
This version is optimized for quick scaffolding from sample JSON rather than deep schema modeling.
Can it handle nested objects?
Yes. Nested objects and arrays are represented in the generated TypeScript shape.
How it works
Turn sample JSON into a quick TypeScript interface for frontend work, demos, and documentation. The result is produced immediately so you can review it before copying or using it elsewhere.
Privacy
The tool is designed to process ordinary input in your browser. Avoid pasting passwords, private keys, access tokens, personal records, or other sensitive production data into any online utility.
Limitations
This utility handles the focused workflow described on this page. Check the result before production use, especially when an input depends on a vendor-specific format, security rule, or external standard.
