What Is JSON to TypeScript Generator?
This tool generates TypeScript interfaces from JSON data samples. It creates named interfaces for nested objects, properly types arrays, and handles primitive types, booleans, and null values automatically.
How to Use
- Paste a sample JSON object into the input field.
- Click "Generate TypeScript" to create the TypeScript interfaces.
- Copy the generated interfaces into your TypeScript project.
Frequently Asked Questions
How are nested objects handled?
Nested objects generate their own interface definitions with auto-generated names based on the parent key.
How are arrays with objects typed?
Arrays containing objects generate a separate interface for the element type, and the array property is typed as the interface name followed by [].
What if my JSON has null values?
Null values are typed as any since the type cannot be determined from null alone.
