Converting between JSON and XML
JSON and XML are both structured data formats, but they serve different ecosystems. JSON is the standard for REST APIs and JavaScript applications. XML remains dominant in SOAP services, configuration files (like Maven pom.xml), and enterprise integrations.
Converting between them is common when integrating modern and legacy systems, migrating APIs from SOAP to REST, or working with data feeds that provide XML but your application expects JSON.
This tool handles attributes (prefixed with @), nested objects, arrays, and mixed content. It uses the browser DOMParser for XML parsing, so no data leaves your device.
Frequently Asked Questions
How are JSON arrays converted to XML?
Each array element is wrapped in an <item> tag. For example, [1,2,3] becomes <item>1</item><item>2</item><item>3</item>.
Does this handle XML attributes?
When converting XML to JSON, attributes are prefixed with @ in the JSON output. When converting JSON to XML, keys starting with @ are treated as attributes.
What about XML namespaces?
Namespaces are preserved as-is in the tag names. The converter does not interpret or transform namespace prefixes.
Can I convert large files?
Yes, though very large files (10MB+) may be slow since processing happens in your browser. For extremely large datasets, a server-side tool would be faster.
