JSON Schema to TypeScript
Generate TypeScript definitions from JSON Schema for strongly typed API contracts
Paste a JSON Schema document. The schema title becomes the default type name.
Generate Types From Schema
This tool converts JSON Schema into TypeScript definitions. It is the cleanest way to keep your runtime contract and your compile-time types from drifting apart like two teams that stopped reading the same wiki.
Use Cases
- Generate TypeScript from API schemas
- Bootstrap client models from shared contracts
- Turn schema-driven mocks into typed code
Frequently Asked Questions
What does JSON Schema to TypeScript generate?
It turns a JSON Schema into TypeScript declarations so you can use the schema as type-safe interfaces or type aliases in your codebase.
Does it preserve enums, required fields, and nested objects?
Yes. The generated output keeps schema structure, required properties, enums, and nested definitions in the emitted TypeScript.
Can I choose the generated type name?
Yes. You can provide a custom interface name, or let the tool derive one from the schema title when available.
Why use this instead of hand-writing types?
Because schemas drift less than human memory. Generate from the source of truth, then refine only where necessary.
Does the generated code run in my browser only?
Yes. The conversion is local, so your schema never leaves the device and you avoid the delightful industry sport of accidental data exposure.
