How to Use the XML to JSON Converter
XML and JSON are the two most common data interchange formats. This tool provides bidirectional conversion between them, preserving your data structure while changing the format.
- Select Direction: Choose XML → JSON or JSON → XML conversion.
- Paste Data: Enter your XML or JSON in the input panel.
- Click Convert: The converted output appears in the right panel.
- Copy Result: Use Copy Output to copy the converted data.
XML vs JSON Comparison
XML Advantages
- • Schema validation with XSD
- • Namespace support for complex documents
- • Mixed content (text + elements)
- • Comments and processing instructions
- • Document-oriented (great for markup)
JSON Advantages
- • Lightweight and compact syntax
- • Native JavaScript integration
- • Easier to parse and generate
- • Data types (numbers, booleans, null)
- • Better for APIs and web services
Common Use Cases
Legacy System Integration
Convert XML from older SOAP services to JSON for modern REST APIs and JavaScript frontends.
Configuration Migration
Transform XML config files to JSON format for Node.js applications or package.json configurations.
Data Processing
Convert RSS feeds, sitemap.xml, or other XML data to JSON for easier manipulation in JavaScript.
Conversion Considerations
Attributes Handling
XML attributes are converted to JSON properties. By default, this tool prefixes attribute names to distinguish them from child elements.
Array Conversion
Repeated XML elements with the same name are automatically converted to JSON arrays. Single elements become single values.
Data Types
XML treats all values as strings. When converting to JSON, numbers and booleans may be automatically detected and converted to their appropriate JSON types.
Frequently Asked Questions
Is conversion always lossless?
Not always. XML features like namespaces, processing instructions, comments, and CDATA sections dont have direct JSON equivalents. The core data structure is preserved, but some XML metadata may be lost.
How are XML namespaces handled?
Namespaces are typically converted as prefixed property names. For example, <soap:Body> might become { "soap:Body":... }. The namespace URI information may be lost unless explicitly preserved.
What happens with mixed content?
Mixed content (text between elements like <p>Hello <b>world</b>!</p>) is challenging to represent in JSON. Text nodes are typically stored in special properties like "#text" or concatenated together.
Why is my conversion different from other tools?
There is no single standard for XML-to-JSON conversion. Different tools make different choices about attribute handling, array detection, and text content. Results may vary between converters.
