The complete guide to XML to JSON Converter

Last updated June 1, 2026

Converting XML to JSON is a common step in API modernization, data pipeline migration, and interoperability work — REST/JSON has largely superseded XML/SOAP, and many legacy data systems still export XML that needs to be consumed by modern JavaScript or Python code. Convertify's XML to JSON converter handles namespaces, attributes, and nested elements, with configurable attribute handling.

The structural mismatch between XML and JSON is the core challenge: XML attributes (e.g., <item id='123'>) and XML elements (e.g., <name>Widget</name>) need to be mapped to JSON properties in a consistent, predictable way. Convertify uses the widely-adopted convention of prefixing attribute names with '@' and element text with '#text' for unambiguous representation.

Step-by-step: how to use XML to JSON Converter

1
Upload or paste XML
Drop an .xml file or paste the XML content. The tool validates the XML structure first.
2
Configure attribute handling
Choose how attributes are represented: '@' prefix convention (default, most compatible), merged with elements (simpler output for simple XMLs), or ignored (attributes dropped).
3
Convert and download
The JSON output previews in the panel. Download as .json or copy to clipboard.

Real-world scenarios

Consuming legacy SOAP API responses

A legacy enterprise system returns SOAP/XML responses. Convert the XML to JSON so the data can be parsed and consumed by modern JavaScript or Python code without an XML parser library.

Data migration from XML-based databases

Older content management systems, ERP platforms, and configuration tools export XML. Convert to JSON for ingestion into modern NoSQL databases (MongoDB, DynamoDB) or REST API endpoints.

RSS/Atom feed processing

RSS feeds are XML. Convert to JSON for building custom feed readers, aggregators, or newsletter tools in JavaScript without maintaining an XML parsing dependency.

Troubleshooting and edge cases

The output JSON has too much nesting — simple elements are wrapped in objects.⌄

This is the natural result of XML's verbose structure. Post-process the JSON with a transformation (like jq or lodash transforms) to flatten to the structure you need. Or use the 'compact' output mode which reduces nesting for simple elements.

Namespaces in the XML are appearing in property names (e.g., 'ns0:element').⌄

XML namespaces are preserved in property names by default for correctness. If namespaces aren't important for your use case, enable 'Strip namespaces' in the converter settings to remove the prefix.

Frequently Asked Questions about XML to JSON Converter - Accurate Structure Mapping Free Online

How are XML attributes represented in the JSON output?

XML attributes are converted to JSON properties prefixed with '@' by default (e.g., @id, @class). You can customize this prefix or flatten attributes alongside child elements.

Does it handle XML namespaces correctly?

Yes. Namespace prefixes are preserved in property names by default. You can also choose to strip namespaces for cleaner output if your use case doesn't require them.

Can I convert large XML files?

Yes. All processing happens in your browser with no server upload. The converter handles large XML documents efficiently, though very large files (100MB+) may depend on your device's available memory.

How are repeated XML elements handled?

Repeated sibling elements with the same tag name are automatically grouped into JSON arrays, which is the natural and expected behavior for most XML-to-JSON use cases.
