XML to JSON

A lot of XML-to-JSON converters are built on regular expressions trying to approximate what an XML parser does, and it usually shows: attributes get dropped or handled inconsistently, malformed XML produces garbage output instead of an error, and edge cases like CDATA sections or entity references (&, <, and similar) get mangled. This tool avoids all of that by using the browser's own DOMParser — the same battle-tested engine that renders XML natively — to actually parse the document, then walking the resulting structure to build JSON from it.

That matters most for attributes, which are where naive converters most often go wrong. This tool represents each attribute as a key prefixed with @ (so <to importance="high"> becomes {"@importance": "high"}), keeping attributes clearly distinguishable from child elements in the resulting JSON — with an option to drop attributes entirely if you only care about the element structure and text content.

Repeated sibling elements are handled the way most JSON consumers expect: a single occurrence of a tag becomes a plain value or object, while multiple occurrences of the same tag under one parent automatically become a JSON array. Text content is captured under a #text key when an element has both attributes or children and its own text, so nothing gets silently dropped.

Because DOMParser doesn't throw JavaScript exceptions on malformed XML — it silently embeds a <parsererror> element in the result instead, a genuine gotcha that trips up naive implementations — this tool explicitly checks for that and surfaces the real parser error message instead of returning an empty or broken result. Everything happens locally: your XML is parsed and converted entirely in the browser tab, never uploaded anywhere.
