XML to JSON Converter

Paste your XML payload to instantly convert it into a clean, formatted JSON object. Our robust client-side parser maps attributes and nested elements efficiently without sending your data to external servers.

XML Input 0 chars
JSON Output 0 chars
Formatted JSON will appear here.

How to Use This Tool

Using our xml to json converter online is designed to be completely frictionless. Simply paste your raw Extensible Markup Language (XML) string—whether it's a legacy SOAP API response, a complex configuration file, or an RSS feed—into the left input pane. Click Convert to JSON, and the utility will immediately parse the document and render beautifully indented JSON in the right pane.

Because this is a free xml to json online tool that operates 100% on the client side, your payloads never leave your browser tab. There are no backend database logs, no external API calls, and zero telemetry pinging. This makes it a highly secure choice when you need to convert xml to json containing sensitive customer data, proprietary cloud infrastructure configurations, or internal API tokens.

XML to JSON Conversion Deep Dive

XML and JSON are structurally different paradigms. XML relies heavily on elements and metadata attributes, whereas JSON maps strictly to key-value pairs, arrays, and primitive data types. Transforming between them without data loss requires a robust mapping strategy.

When you use our xml2json tool, the native browser xml parser (specifically the DOMParser API) generates a Document Object Model tree. We then traverse this tree and map the nodes into a JSON object using these standard developer conventions:

  • Attributes: XML attributes (e.g., <node id="123">) are grouped under a special _attributes key in the resulting JSON object to prevent namespace collisions with child elements.
  • Text Content: If an element contains only text, it directly maps as a string value. If an element contains both text and attributes, the text content is neatly preserved under a _text key.
  • Arrays: Since XML doesn't have an explicit array syntax, multiple sibling elements sharing the exact same tag name (like a list of <item> tags) are automatically grouped into a single JSON array structure.

This deterministic approach guarantees that when you integrate or debug legacy systems alongside modern RESTful endpoints, the translated payload remains highly predictable and ready for ingestion by modern JavaScript frontends or serverless JSON databases.
