XML to JSON

Convert XML to JSON with attributes, arrays and typed values

XML is still what many feeds, exports and enterprise systems produce, while almost every modern program wants JSON. XML to JSON converts an XML document into JSON using clear rules, so the result is predictable and easy to code against.

Paste the XML or drop an .xml file. Each element becomes an object keyed by its name; attributes become keys prefixed with @; text that sits next to child elements is kept under #text; an element that appears more than once under the same parent becomes an array; an empty element becomes null. Namespace prefixes are removed from names so that keys stay simple. Values that look like numbers or booleans are converted, which is right for most data feeds; choose to keep everything as text when identifiers such as product codes with leading zeros must survive untouched. Invalid XML is reported with the position of the error.

The conversion is designed to be reversible: JSON to XML understands the same @ and #text conventions and writes the elements back. For configuration files in YAML use YAML to JSON, and to check what changed between two exports run the results through Compare JSON.
