JSONFlattener

Flattens JSON (JavaScript Object Notation) objects, extracting the object keys and values into FME feature attributes.

For example, consider a feature which has an attribute named json containing the following text:

{
   "paramName":"GeocodeResult",
   "dataType":"GPFeatureRecordSetLayer",
   "value":
   {
      "geometryType":"esriGeometryPoint",
      "spatialReference": {"wkid":4326 }
   }
}

After going through the JSONFlattener, the following attributes will have been added to the feature:

Attribute Name Attribute Value
paramName GeocodeResult
dataType GPFeatureRecordSetLayer
value.geometryType esriGeometryPoint
value.spatialReference.wkid 4326
