XML to JSON Converter Online

Convert XML to JSON format. Fast, secure, and completely free. All processing happens in your browser — no data is sent to any server.

What is XML to JSON?

XML to JSON conversion parses an XML document's element tree and produces an equivalent JSON representation, mapping elements to object keys, attributes to a designated attribute field, and text content to string values. Because XML and JSON model data differently — XML has both elements and attributes plus mixed content, while JSON has only nested objects, arrays, and primitive values — this conversion necessarily makes some structural choices (like how attributes are represented), which is worth understanding rather than assuming is automatic and lossless in every edge case.

How to Use XML to JSON

1. Paste your XML document into the input panel
2. Click 'Convert' to parse it and produce the equivalent JSON structure
3. Review how attributes were mapped — typically under an @attributes or similarly named key
4. Copy the resulting JSON for use in a JavaScript application or JSON-based API
5. Use JSON to XML to convert back if you need to round-trip the data

Key Features

• Converts XML elements, attributes, and text content into a structured JSON object
• Configurable attribute-key naming convention (e.g. @attr or _attr prefix)
• Handles repeated sibling elements by converting them into JSON arrays
• Supports namespaced XML elements
• Runs entirely client-side, safe for internal data exports

Why Use XML to JSON?

Plenty of legacy systems, SOAP APIs, and older data exports still use XML, but modern frontend and API tooling is overwhelmingly JSON-first. Converting an XML response or config into JSON is often the necessary bridge step before you can work with that data comfortably in JavaScript, feed it into a JSON-based validation or transformation tool, or store it in a document database that expects JSON natively.

Common Use Cases

• Converting a legacy SOAP API's XML response into JSON for a modern frontend
• Migrating an XML-based configuration file to a JSON-based system
• Preparing XML data exports for ingestion into a JSON document database
• Making an XML-based data feed easier to process in JavaScript
• Converting an XML sitemap or RSS feed into JSON for programmatic use

Frequently Asked Questions

How are XML attributes represented in the resulting JSON?

Attributes are typically nested under a dedicated key (often @attributes or similarly prefixed) separate from the element's child content and text, since JSON has no native concept of attributes distinct from regular object fields.

What happens to repeated sibling elements with the same tag name?

They're converted into a JSON array, since JSON objects can't have duplicate keys the way XML can have multiple sibling elements with the same tag name.

Is the conversion always perfectly reversible back to the original XML?

Not always exactly byte-for-byte — some XML-specific nuances like comments, processing instructions, or unusual mixed content (text interspersed with child elements) don't have a clean JSON equivalent, so round-tripping through JSON to XML may not reproduce the identical original document.

Does it handle XML namespaces correctly?

Yes, namespaced elements and attributes are preserved in the conversion, typically retaining their prefix in the resulting JSON keys.

Is my XML data uploaded anywhere to be converted?

No, parsing and conversion happen entirely in your browser using JavaScript.
