Bidirectional converter between XML and JSON with attribute and nested element support

Your API Returns XML. Your Frontend Expects JSON. Welcome to Enterprise Integration.

XML isn’t dead. It’s still powering SOAP APIs, RSS feeds, legacy enterprise systems, and half the configuration files in Java-land. But modern web development speaks JSON. When these two worlds collide — and they collide daily in integration work — you need a reliable way to convert between them without losing attributes, nesting, or array structures.

The XML JSON Converter handles both directions: XML to JSON and JSON to XML. It preserves XML attributes as @-prefixed JSON keys (so <item id="1"> becomes {"@id": "1"}), automatically groups repeated sibling elements into JSON arrays, and handles deeply nested structures. It uses the browser’s built-in DOMParser for XML handling, which means parsing is reliable and your data never leaves your device.

How Attributes and Arrays Work

This is where most XML-to-JSON converters trip up. XML has attributes, text content, and child elements — concepts that don’t map neatly to JSON’s key-value structure. This converter uses a clear convention:

  • XML attributes become @-prefixed keys: <book id="1"> maps to {"@id": "1"}
  • Text content becomes #text when it coexists with child elements or attributes
  • Repeated sibling elements are automatically grouped into arrays: multiple <item> tags become a JSON array of item objects
  • Deep nesting is preserved accurately in both directions

Using It

  1. Pick the direction — XML to JSON or JSON to XML
  2. Paste your data
  3. Click Convert
  4. Copy the result or Swap to reverse

Paste <book id="1"><title>Clean Code</title><author>Robert Martin</author></book> and get {"book": {"@id": "1", "title": "Clean Code", "author": "Robert Martin"}}. Clean and predictable.

Real Integration Scenarios

  • SOAP to REST migration — you’re modernizing an API and need to translate XML response structures into JSON equivalents
  • Older enterprise systems export XML data that modern applications consume as JSON — this converter bridges the gap during migration
  • RSS and Atom feed processing where you need to parse XML feeds into JSON for a JavaScript-based aggregator
  • Converting XML configuration files to JSON for Node.js projects that expect JSON config
  • ETL workflows where data moves between XML-based and JSON-based systems

What It Won’t Do

Processing instructions, XML comments, and CDATA sections may not survive a round-trip. The converter preserves semantic content — attributes, text, structure — but XML-specific syntactic features that have no JSON equivalent get dropped. For most data interchange work, this is fine. For document-oriented XML with embedded comments and processing instructions, you might lose some metadata.

The CSV JSON Converter handles tabular data conversion. The YAML JSON Converter bridges configuration formats. The Document Converter hub links to all format tools.

Specifics

Is the @ prefix convention standard?

It’s the most commonly used convention for representing XML attributes in JSON. Other tools and libraries use the same approach, so the output is interoperable with most XML-to-JSON processing workflows.

What about CDATA sections?

CDATA content is treated as text content. The CDATA wrapper itself doesn’t carry over to JSON since JSON doesn’t have an equivalent concept.

Is it safe for sensitive data?

Everything processes in your browser using the built-in DOMParser. No data gets sent to any server. Safe for proprietary XML, API responses, and configuration files.

Cost?

Free, no accounts, no restrictions.
