Features
 
  •  Turn a JSON object or array into well-formed XML
  •  Keys starting with @ become attributes
  •  Arrays become repeated sibling elements
  •  Choose the root element name
  •  Configurable indent
  •  Runs locally. API dumps never leave the tab
 
Common Use Cases
 
  •  Build a test SOAP-like envelope from a JSON fixture
  •  Export app state as XML for a legacy importer
  •  Wrap a JSON array in a root so XML tools can parse it
  •  Generate Android-style nested resources from JSON
  •  Round-trip after XML to JSON for a sanity check
 
How JSON keys become tags
 
Each object key becomes an element name after a sanitize pass (illegal characters become underscores). Arrays emit the same tag once per item. @id style keys become attributes. #text becomes character data.


JSON arrays at the top level need a root wrapper because XML allows only one document element. Set the root name to something your consumer expects (items, catalog).
 
Examples
 
 Valid - Object with attribute
 
{"@id":"1","title":"Go"}
 Valid - Array needs a root
 
[{"n":1},{"n":2}]
 Invalid - Invalid JSON
 
{id:1}
  
Frequently Asked Questions
 
 
Why was my key renamed?
 
XML names cannot start with a digit or contain spaces. We rewrite those characters so the output still parses.
 
Do I get an XML declaration?
 
Yes, UTF-8. Remove it if your host already wraps the payload.

 Tips
 
  •  Use @keys for attributes if you plan to round-trip.
  •  Pick a root name that matches the target schema, not a generic "root", when you can.
