What does JSON formatting do?

JSON formatting adds proper indentation, line breaks, and spacing to make JSON data more readable while maintaining the same data structure and content.

When should I minify JSON?

Minify JSON for production environments, API responses, and file storage to reduce bandwidth and storage requirements by removing unnecessary whitespace.

How does JSON validation work?

The validator checks JSON syntax according to the official specification and reports errors with specific line and column numbers to help you fix issues quickly.

Can I format large JSON files?

Yes, the formatter handles large JSON files efficiently. However, very large files may affect browser performance, so consider using command-line tools for extremely large datasets.
