Frequently Asked Questions

Can this tool generate TypeScript interfaces from JSON?
Yes. Along with beautifying and minifying JSON data, the tool automatically infers property types, nested objects, and arrays to generate production-ready TypeScript types.
Is my JSON data kept private?
Yes. All parsing, validation, formatting, and type inference run strictly within your local JavaScript runtime without transmitting data to any server.
What happens if my JSON syntax has an error?
The validator catches syntax errors, unclosed brackets, missing quotes, or trailing commas and displays exact line and column locations.
