What Is a XML to JSON Converter?
Converting XML to JSON is essential when modernizing legacy systems, consuming SOAP API responses in JavaScript applications, or migrating data from XML-based formats to JSON-based databases like MongoDB or Firebase. Many government and enterprise data feeds still use XML, while modern frontends expect JSON. This converter parses XML into a clean JSON structure, handling attributes, namespaces, and nested elements.
Example
XML Input:
<?xml version="1.0"?>
<user>
<name>Alice</name>
<age>30</age>
</user>JSON Output:
{"user":{"name":"Alice","age":"30"}}How to Use This Converter

Frequently Asked Questions
How are XML attributes converted to JSON?
XML attributes are typically prefixed with '@' or '_' in the JSON output. For example, <user id='1'> becomes {"user": {"@id": "1"}}. The exact convention varies by converter — this tool uses the '@' prefix.
What happens to XML namespaces during conversion?
XML namespaces (xmlns attributes) are either preserved as prefixed keys or stripped depending on the converter. For most use cases, stripping namespaces produces cleaner JSON. Complex namespace handling may require specialized XML parsing libraries.
Can XML comments be preserved in JSON?
No — JSON has no comment syntax. XML comments (<!-- ... -->) are stripped during conversion. If you need to preserve metadata, consider adding it as a data field instead.
How is CDATA handled in the conversion?
CDATA sections in XML (<![CDATA[...]]>) contain raw text that shouldn't be parsed as XML. During conversion, the CDATA content is extracted as a plain string value in JSON, with the CDATA wrapper removed.
