XML to JSON Converter Free Online

Free online XML to JSON converter. Paste XML data and instantly convert it to JSON format in your browser.

JSON output...

How it works

  • XML elements become JSON keys
  • XML attributes become @attrName keys
  • Repeated elements become arrays
  • Text content is preserved as strings

XML remains widely used in enterprise systems, government APIs, SOAP web services, RSS/Atom feeds, Microsoft Office document formats, and many legacy integrations. When you need to work with XML data in a modern web application, JavaScript project, or REST API, converting it to JSON makes the data immediately usable without specialised XML parsing libraries. This free XML to JSON converter handles the transformation instantly in your browser, supporting complex XML with attributes, namespaces, nested elements, and repeated elements.

How to Use the XML to JSON Converter

1

Paste your XML document

Paste your XML content into the input field. The converter accepts complete XML documents (with XML declaration and root element) or XML fragments. It supports all standard XML constructs including elements, attributes, text content, CDATA sections, namespaces, and comments.

2

Click Convert to JSON

Click the Convert button. The tool parses the XML document structure and recursively converts each element, attribute, and text node to its JSON equivalent. The conversion preserves the hierarchical structure of the XML - nested elements become nested JSON objects, and sibling elements with the same tag name become JSON arrays.

3

Copy or download the JSON

The converted JSON appears in the output panel with proper formatting and indentation. Click Copy to copy it to your clipboard or Download to save it as a .json file. Use the output in your JavaScript application, API integration, database import, or data processing pipeline.

How XML Elements Convert to JSON

XML and JSON have different structural models, so some conventions are needed to represent XML faithfully in JSON. Here is how the converter handles the main XML constructs:

XML elements - each XML element becomes a JSON property named after the element's tag name. If an element has only text content (no child elements), the text becomes the property's string value. If an element has child elements, it becomes a nested JSON object.

XML attributes - attributes on XML elements are converted to JSON properties with @ prefixes (e.g., <user id="123"> becomes {"@id": "123", ...}). This convention distinguishes attribute-derived properties from element-derived properties.

Repeated elements - when multiple XML sibling elements share the same tag name, they are automatically converted to a JSON array. For example, multiple <item> elements become a JSON array [{...}, {...}, {...}].

Mixed content - elements with both text and child elements have their text content stored in a special "#text" property alongside the child element properties.

Namespaces - namespace prefixes are preserved in the JSON property names (e.g., <soap:Body> becomes a property named "soap:Body").

Common Use Cases for XML to JSON Conversion

SOAP to REST migration - many enterprise systems expose SOAP APIs that return XML. Converting SOAP responses to JSON makes them usable in modern JavaScript applications and REST-based architectures without requiring SOAP client libraries.

RSS/Atom feed processing - RSS and Atom feed formats are XML-based. Converting feed data to JSON simplifies processing in Node.js, Python, and other modern environments where JSON is more native.

Government and financial data - many government open data portals and financial reporting standards (XBRL for financial reporting) use XML. Converting these to JSON enables analysis in modern data science tools and web applications.

Configuration file migration - some systems use XML configuration files (Maven pom.xml, Android manifest.xml, Spring application context). Converting to JSON facilitates migration to JSON-based configuration systems.

Frequently Asked Questions

How are XML attributes represented in the JSON output?
XML attributes are converted to JSON properties prefixed with the @ symbol. For example, <user id="123" name="John"> becomes a JSON object with "@id": "123" and "@name": "John" as properties. This convention (popularised by the BadgerFish convention) clearly distinguishes attribute properties from child element properties in the JSON output.
How are repeated XML elements handled?
When multiple sibling elements have the same tag name, they are automatically converted to a JSON array. For example, multiple <product> elements become "product": [{...}, {...}, {...}]. Single occurrences of an element remain as objects. This is the most natural JSON representation of XML lists and collections.
Does it support XML namespaces?
Yes. XML namespace prefixes are preserved in the JSON property names. For example, <soap:Envelope xmlns:soap="..."> produces a JSON property named "soap:Envelope". The namespace declarations themselves (xmlns attributes) are included as @xmlns properties. This allows the JSON output to faithfully represent the original namespace structure.
Can it handle large XML documents?
Yes. All XML parsing and conversion occurs in your browser. The limit is your device's available memory rather than any server-side restriction. The browser's native DOMParser API is used for XML parsing, which is efficient and can handle XML documents of many megabytes without issues on modern devices.
Is my XML data sent to a server?
No. All conversion happens entirely in your browser. Your XML data never leaves your device and is never transmitted to any external server. This makes the tool safe for converting sensitive XML documents such as financial reports, personal data exports (GDPR access requests often come in XML), healthcare records, internal configuration files, and any proprietary business data.
