### Can this tool validate JSON?

Yes. The formatter automatically validates your JSON and highlights any syntax errors with descriptive error messages, helping you quickly find and fix issues.

### What is the difference between formatting and minifying JSON?

Formatting (pretty-printing) adds indentation and line breaks to make JSON human-readable. Minifying removes all whitespace to create the smallest possible file size, ideal for APIs and data transfer.
