Question 1

How does JSON to TypeScript conversion work?

Accepted Answer

Paste a JSON object and the tool analyzes the structure, data types, and nesting to generate TypeScript interfaces. Arrays are typed based on their contents, and nested objects get their own named interfaces.

Question 2

Does it handle optional fields?

Accepted Answer

The tool generates interfaces based on the sample data provided. If a field is present, it's marked as required. For optional fields, you'll need to add the ? modifier manually after reviewing the generated types.

Question 3

Can I generate types from API responses?

Accepted Answer

Absolutely — that's one of the most popular uses. Copy a JSON API response, paste it in, and get TypeScript interfaces ready to use in your frontend code. This saves significant time when working with REST APIs.

Question 4

What TypeScript types are generated for JSON values?

Accepted Answer

Strings become string, numbers become number, booleans become boolean, null becomes null, arrays become typed arrays (e.g., string[]), and objects become named interfaces with all their properties.
