Frequently Asked Questions
How are JSON arrays converted to XML?
JSON array items are wrapped in <item> tags. Object keys become XML element names. Nested objects and arrays are recursively serialized.
How are XML attributes handled?
The XML → JSON parser treats element content as values. XML attributes are not currently extracted separately — only text content and child elements.
Is my data uploaded to a server?
No. All conversion runs entirely in your browser using the built-in DOMParser and JavaScript. Your files never leave your device.
What happens with invalid XML?
If the XML cannot be parsed, a clear error message is shown. Check for unclosed tags or invalid characters and try again.
