JSON Schema to TypeScript — Convert a Schema Definition, Not an Example

Paste an actual JSON Schema definition (not a JSON data example) to generate matching TypeScript interfaces — this is a different job from inferring types from example data, since a schema already explicitly states each field's type, required status and constraints, which translates far more precisely than inference from a single example can.

How to use JSON Schema to TS

1. Paste your JSON Schema definition.
2. Review the generated TypeScript interfaces.
3. Copy them into your project.

Frequently asked questions

How is this different from JSON to TS?

JSON to TS infers types from an example data object, guessing at what is required. This converts an actual JSON Schema, which already explicitly declares types, required fields and constraints — so the result is more precise, not a guess.

Does it support schema features like enums and oneOf?

Yes — JSON Schema constructs like enum, oneOf and const are translated to their TypeScript equivalents (union types, literal types) rather than being flattened away.

What JSON Schema draft does it accept?

Modern drafts (2019-09/2020-12 style) are supported, matching what most current schema tooling generates.
