A device is configured to receive information that identifies an XML data structure, an input key including information that identifies an element in the XML data structure, and an output key including information that identifies a manner in which the element is to be identified in a JSON data structure. The device is configured to parse the XML data structure to determine an element identified by the input key, and generate the JSON data structure by storing an association between the element and the output key in the JSON data structure. The device is configured to populate the JSON data structure with content from the XML data structure, where the content is identified by the input key and is placed in a location in the JSON data structure identified by the output key. The device is configured to store the JSON data structure.
