json_path

json_path extracts an element from a JSON document using JSONPath. The input token must be a JSON document and the JSONPath must be valid. Note that we use the excellent gjson library but not all JSONPath combinations are supported. Check the GitHub page to see if a more complicated JSONPath is supported.

If the key does not already exist then it is inserted as a string object type into the desired location. Creating nested arrays using JSONPath array notation (ex: foo.[0]) is also supported. To turn off this functionality set create=false.
