JSON to TypeScript
Generate TypeScript interfaces or type aliases from JSON examples.
About JSON to TypeScript
TypeScript interfaces and type aliases define the shape of data, enabling type checking and IDE autocompletion. Manually writing types for complex JSON structures is tedious and error-prone. This tool automatically infers TypeScript definitions from JSON examples, handling nested objects, arrays, optional fields, and union types.
How to Use
Paste a JSON example in the input area and set the root type name (default: "Root"). Choose between "interface" and "type" output style. Click "Generate" to create the TypeScript definition. Nested objects automatically generate sub-types. Copy the output with one click.
Common Use Cases
- Generating types from API response examples for frontend development
- Creating interfaces from database query results
- Building type definitions for configuration files
- Converting JSON schemas to TypeScript for form validation
- Quickly scaffolding types during rapid prototyping
