Frequently Asked Questions
Why does JSON need a root tag when converting to XML?
XML specification (W3C standard) strictly requires all documents to have exactly one single root element enclosing all other elements. JSON arrays and multi-key objects must be wrapped in a root container like <root>...</root>.
How are special characters escaped in XML output?
Characters that have syntactic meaning in XML are escaped: '&' becomes '&', '<' becomes '<', '>' becomes '>', '"' becomes '"', and single quotes become '''.
How are JSON arrays translated into XML elements?
Each item in a JSON array is wrapped in a dedicated child tag (e.g. an array of items [1, 2, 3] becomes <item>1</item><item>2</item><item>3</item> inside its parent tag).
