How to Generate TypeScript From JSON

Turn sample JSON into a starting interface quickly and then refine it as your data model becomes clearer.

Start from real sample data

A sample payload often gives you enough structure to create a useful first interface. That is faster than writing every property by hand from memory.

Treat generated types as a first pass

Quick generators are most valuable when they remove repetitive setup work. You can still refine names and optional fields once the base shape exists.

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.
