JSON to TypeScript Converter
Generate TypeScript interfaces from JSON data automatically
What is a JSON to TypeScript converter?
A JSON to TypeScript converter analyzes JSON data and automatically generates TypeScript interfaces that match the structure and types of your data, saving you time and reducing errors.
How do I convert JSON to TypeScript?
Paste your JSON data into the input field, optionally customize the root interface name, and click 'Convert to TypeScript'. The tool will generate TypeScript interfaces instantly.
Why convert JSON to TypeScript?
Converting JSON to TypeScript interfaces provides type safety, better IDE autocomplete, compile-time error checking, and improved code documentation. It's essential for TypeScript projects consuming JSON APIs.
Does the converter handle nested objects?
Yes! The converter automatically generates separate interfaces for nested objects and arrays, creating a complete type hierarchy that matches your JSON structure.
Can I customize the interface names?
Yes! You can set a custom name for the root interface. Nested interfaces are automatically named based on their property keys for clarity and consistency.
What types does the converter support?
The converter recognizes string, number, boolean, null, arrays, and nested objects. It generates appropriate TypeScript types for each, including array types and nested interfaces.
Can I convert large JSON files?
Yes, the converter handles JSON of various sizes efficiently. Very large files (over 10MB) may take a moment to process depending on your device's performance.
Is my data secure when using this tool?
Absolutely! All conversion happens entirely in your browser using JavaScript. Your JSON data never leaves your computer, ensuring complete privacy and security.
Does the tool work offline?
Yes! Once the page is loaded, the converter works completely offline. All processing happens locally in your browser without requiring an internet connection.
Can I use the generated interfaces in my project?
Yes! The generated TypeScript interfaces are ready to use. Simply copy them into your TypeScript files and they'll provide full type safety for your JSON data.
