Frequently Asked Questions

XML attributes are preserved in the JSON output within an "@attributes" object. This ensures no data loss while maintaining a clear distinction between element content and attribute data in the converted JSON structure.

Yes! The converter handles complex XML including namespaces, deeply nested elements, mixed content, and CDATA sections. The hierarchical structure is preserved in the resulting JSON object format.

Use pretty printing for development, debugging, and human-readable configuration files. Use compact output for production APIs, data storage, and network transmission where smaller file size is important.
