If the array looks like this:

DataRobot will treat it as a text variable, which would be processed using common NLP techniques such as n-grams and TF-IDF transformation.

 

And if the array looks like this:

DataRobot will treat it as a summarized categorical variable, which DataRobot will create column for each key & value pairs.
