XML to JSON Converter
Appliance Location: The Food Processor Data TransformationHow to Convert XML to JSON
Converting XML data to JSON format is simple with our online converter. Follow these steps:
- Enter XML Data: Paste your XML code into the input panel above. Load an example to see how it works.
- Configure Options: Choose conversion preferences — pretty print, include attributes, trim text, auto-detect numbers/booleans.
- Convert & Copy: Click "Convert to JSON" and copy or download the resulting JSON output.
Why Convert XML to JSON?
JSON has become the dominant data interchange format for modern web development. It's lighter, faster to parse, and more compatible with JavaScript frameworks. Converting XML to JSON offers several advantages:
- API Modernization: Legacy APIs often return XML. Convert responses to JSON for easier integration with modern frontend frameworks.
- Reduced Payload Size: JSON is typically 30-40% smaller than equivalent XML, reducing bandwidth usage.
- Faster Parsing: JSON.parse() is significantly faster than XML DOM parsing for large datasets.
- Better Compatibility: JSON is natively supported in JavaScript, Python, PHP, Java, and all major languages.
XML vs JSON: Key Differences
- XML: Uses tags like HTML, supports attributes, requires closing tags, handles mixed content, supports namespaces.
- JSON: Uses key-value pairs like JavaScript objects, lightweight syntax, no closing tags required, native array support.
XML to JSON Conversion Rules
- Elements become objects: XML elements are converted to JSON object keys.
- Attributes become properties: XML element attributes become JSON properties with an "@" prefix.
- Text content becomes value: Element text content becomes a "#text" property or direct value.
- Repeated elements become arrays: Multiple sibling elements with the same name become JSON arrays.
- CDATA preserved: CDATA sections are preserved as text content.
Privacy-First Client-Side Processing
Your privacy is our priority. All XML to JSON conversion happens locally in your browser using JavaScript. Your data never leaves your device — no server uploads, no data storage, no third-party access. This makes our converter ideal for processing sensitive data, proprietary XML schemas, or confidential API responses.
XML to JSON Conversion Examples
| XML Structure | JSON Output | Use Case |
|---|---|---|
<user>John</user> |
{"user": "John"} |
Simple value |
<user id="123">John</user> |
{"user": {"@id": 123, "#text": "John"}} |
Element with attribute |
<users><user>John</user><user>Jane</user></users> |
{"users": {"user": ["John", "Jane"]}} |
Repeated elements → array |
<book><title>JS</title><author>Jane</author></book> |
{"book": {"title": "JS", "author": "Jane"}} |
Nested elements → object |
Frequently Asked Questions
What is the difference between XML and JSON?
XML uses tags and attributes with a document-style format, supporting comments, CDATA, and namespaces. JSON uses key-value pairs with a simpler, lighter syntax native to JavaScript. JSON is generally preferred for web APIs due to smaller size and faster parsing.
Is my XML data sent to a server?
No, absolutely not. Our XML to JSON converter processes everything locally in your browser. Your data never leaves your device — no server uploads, no data storage, complete privacy.
How are XML attributes handled in JSON?
When "Include XML Attributes" is enabled, attributes are converted to JSON properties with an "@" prefix. For example, <user id="123"> becomes {"user": {"@id": 123, "#text": "value"}}.
How are repeated elements converted?
Repeated sibling elements with the same name are converted to JSON arrays. Example: <users><user>John</user><user>Jane</user></users> becomes {"users": {"user": ["John", "Jane"]}}.
Can I convert large XML files?
Yes, our converter handles large XML files efficiently. Since processing happens in your browser, limits depend on your device memory. Most browsers can comfortably convert files up to 10-20MB.
Is this tool free to use?
Yes, completely free with no usage limits, no registration, no watermarks. Convert as much XML as you need. The tool is ad-supported but your privacy remains protected as no data leaves your browser.
