Frequently Asked Questions
XML attributes are mapped to properties prefixed with '@_' by default. For example, <item id="5"> becomes {"item": {"@_id": "5"}}.
When an element name appears multiple times under the same parent, the values are collected into a JSON array automatically.
Namespace prefixes are included in the property names. For example, <ns:element> becomes the key 'ns:element' in the JSON output.
CDATA content is extracted as plain text. The CDATA wrapping is removed, and the inner content becomes a string value.
No. XML comments are stripped during conversion because JSON does not support comments.
Yes. The parser handles files up to several hundred megabytes depending on your device's memory. The conversion runs entirely in the browser.
In most cases, yes. You can convert the JSON back to XML using the JSON to XML converter. However, some XML-specific features like processing instructions and DOCTYPE declarations are not preserved.
Elements with both text and child elements have the text stored in a '#text' property alongside the child element properties.
The XML declaration (<?xml version="1.0"?>) and DOCTYPE are parsed but not included in the JSON output since they are metadata, not data.
