XML vs JSON Comparison

Understanding the differences between XML and JSON helps you choose the right format for your projects.

XML uses opening and closing tags to define elements, creating a verbose but highly descriptive structure. Each piece of data requires both a start tag and end tag, which increases file size but provides excellent self-documentation. XML supports attributes within tags, namespaces for avoiding naming conflicts, and schemas for strict validation.

JSON organizes data in key-value pairs using curly braces for objects and square brackets for arrays. The syntax requires less markup overhead, typically producing files 30-40% smaller than equivalent XML documents. JSON integrates natively with JavaScript and most modern programming languages without requiring additional parsing libraries.

When to Choose XML: Use XML for document-centric data, configurations requiring comments, systems needing schema validation, or integration with SOAP web services.

When to Choose JSON: Use JSON for web APIs, mobile applications, NoSQL databases, real-time data exchange, and JavaScript-heavy applications.

Common Conversion Rules

The converter applies standard transformation rules to produce consistent JSON output from XML input.

Elements become properties: Each XML element translates to a JSON property with the element name as the key. Child elements become nested objects within the parent property.

Attributes use prefixes: XML attributes convert to JSON properties with a configurable prefix (typically @ or _) to distinguish them from child elements.

Text content handling: Element text content appears as a #text property when the element also contains attributes or child elements. Simple text-only elements convert directly to string values.

Repeated elements form arrays: Multiple sibling elements sharing the same name automatically combine into a JSON array, preserving their original order.

Empty elements: Self-closing or empty XML elements convert to null values or empty strings depending on context.
