What happens to XML attributes during conversion?

XML attributes are preserved in the JSON output with an '@' prefix. For example, becomes { '@id': '1' }. This ensures no data is lost during conversion.

How are repeated XML elements handled?

When the same element tag appears multiple times at the same level, they're automatically converted to a JSON array. For example, multiple elements become an array of items.

Is there a size limit for XML input?

No, there's no size limit. All conversion happens locally in your browser using the built-in DOMParser API, so it can handle large XML documents without any server upload.
