JSON vs XML: Key Differences
| Feature | JSON | XML |
|---|---|---|
| Readability | Compact, easy to read | Verbose, self-describing |

| Arrays | Native support | Repeated elements (no array syntax) |
| Attributes | Not supported | Native support |
| Use Cases | REST APIs, web apps, config files | SOAP APIs, RSS, SVG, config files |

Frequently Asked Questions
How are JSON arrays converted to XML?▼
JSON arrays are converted to repeated XML elements with the same tag name. For example, "colors": ["red", "blue"] becomes <colors>red</colors><colors>blue</colors>. When converting back, repeated elements are automatically detected and converted to arrays.
How are XML attributes handled?▼
When converting XML to JSON, attributes are prefixed with @. For example, <person id="1"> becomes {"@id": "1"}. Text content of elements with attributes is stored in #text.
Is the conversion lossless?▼
JSON to XML conversion is generally lossless for common data structures. However, XML to JSON conversion may lose some information like comments, processing instructions, CDATA sections, and namespace prefixes. Data types in JSON (numbers, booleans) become text in XML and are heuristically parsed when converting back.
What is the root element name for?▼
XML requires a single root element wrapping all content. When converting JSON to XML, you can specify this root element name (defaults to "root"). For example, if your JSON represents a user, you might set it to "user" for more meaningful XML output.
