Frequently Asked Questions
What is JSON to TypeScript conversion?
JSON to TypeScript conversion generates TypeScript interface definitions from JSON data. Instead of manually writing interfaces that mirror your API responses or config files, the converter infers string, number, boolean, array, and nested object types automatically.
Does the converter handle nested JSON objects?
Yes. Deeply nested JSON objects are converted to multiple linked TypeScript interfaces, with each nested object getting its own interface definition.
Can I convert JSON arrays to TypeScript?
Yes. JSON arrays are converted to typed TypeScript arrays such as string[], number[], or YourInterface[] based on the inferred element types.
Is this tool free?
Yes, completely free with no account required.
Does JS2TS store my JSON data?
No. Your data is processed in real time and never stored or logged on our servers.
