XML to JSON Converter

What is XML to JSON Converter?

XML to JSON Converter is a free online tool that transforms XML (Extensible Markup Language) data into JSON (JavaScript Object Notation) format. It intelligently maps XML elements, attributes, and text content to equivalent JSON structures, making it easy to migrate data between systems that use different formats.

Why Would You Need to Convert XML to JSON?

• API Modernization: Convert legacy XML APIs to modern JSON-based REST APIs
• Web Development: Transform XML data for use in JavaScript applications that expect JSON
• System Integration: Bridge communication between XML-based and JSON-based services
• Data Migration: Move data from older XML-based systems to modern JSON databases
• Reduced Payload Size: JSON is typically smaller than equivalent XML, reducing bandwidth usage

How to Convert XML to JSON - Step by Step

1. Input Your XML: Paste your XML data or upload an XML file
2. Configure Options: Select how to handle attributes, namespaces, and text nodes
3. Click Convert: Press the convert button to transform XML to JSON
4. Get Your JSON: Copy the resulting JSON or download it as a file

Key Features

• Attribute Handling: Converts XML attributes with configurable prefix (default @)
• Array Detection: Automatically detects repeated elements and converts them to JSON arrays
• Namespace Support: Handles XML namespaces with optional prefix preservation
• Text Content Mapping: Properly handles mixed content and text nodes
• Pretty Output: Generates formatted, readable JSON output

Tips for Best Results

• Validate your XML before conversion to avoid errors from malformed markup
• Understand how attributes will be converted - they become prefixed properties in JSON
• Review the output structure, as XML's hierarchical nature may create deeply nested JSON

Frequently Asked Questions

How are XML attributes converted?

XML attributes are converted to JSON properties with a prefix (typically @). For example, an attribute id="123" becomes "@id": "123" in JSON. You can customize this behavior in the settings.

What happens to repeated XML elements?

When the same element name appears multiple times (siblings), they are automatically grouped into a JSON array. Single occurrences remain as regular objects.

Can I convert XML with namespaces?

Yes, the converter handles XML namespaces. You can choose to preserve namespace prefixes in the JSON keys or strip them for cleaner output, depending on your needs.
