XML to JSON

Example: repeated XML elements become a JSON array

Choose Compact objects for the mapping below. The ordered mode serves a different purpose: retaining child-node order when text and elements are mixed.

Example input

<items><item id="a">One</item><item id="b">Two</item></items>

Expected result

{"items":{"item":[{"@attributes":{"id":"a"},"#text":"One"},{"@attributes":{"id":"b"},"#text":"Two"}]}}

Common questions and errors

Which mode should I use for mixed content?

For <p>Hello <b>world</b>!</p>, use Ordered node tree when the sequence of text and child elements matters. Compact objects are convenient for data-like XML but do not model every ordering detail.

Why are numbers still strings?

XML element text and attribute values are text. This converter does not guess a numeric or boolean type, so an ID such as 00123 is not silently changed.

DOCTYPE is rejected

Documents containing DOCTYPE or ENTITY declarations are intentionally rejected. Use XML that does not depend on a DTD or external entity definitions.
