What Is a TypeScript to JSON Schema Converter?
This tool converts TypeScript interfaces into JSON Schema format. JSON Schema is a vocabulary for annotating and validating JSON data, widely used for API documentation, form validation, and configuration file validation. By converting your TypeScript types, you get a schema that can be used with validators, API gateways, and documentation tools.
How to Use This Converter
- Paste a TypeScript interface definition in the input area.
- Click "Convert to JSON Schema" to generate the schema.
- Copy the output JSON Schema for use in your project.
Supported TypeScript Types
This tool supports basic TypeScript types: string, number, boolean, any, optional properties (?), and arrays (type[] or Array<type>). It also recognizes null and union types with null (e.g., string | null).
Frequently Asked Questions
Does this handle nested interfaces?
This tool parses a single interface at a time with flat property types. For nested objects, define them as separate interfaces and combine the schemas manually, or use inline object types within the interface.
What JSON Schema version is generated?
The output follows JSON Schema Draft-07 (http://json-schema.org/draft-07/schema#), which is the most widely supported version across validators and tools.
