Frequently Asked Questions
How does the JSON to TypeScript conversion work?
The tool analyzes the JSON structure and generates TypeScript interfaces that match it. Objects become interfaces, arrays are typed by their contents, and primitive values become string, number, or boolean types.
Does it handle nested objects?
Yes. Each nested object gets its own named interface (using the parent key name in PascalCase), and the parent interface references it by name.
