Hi @claraosuna, a possible way is to expose the list members ("array{}.date", "array{}.id", "array{}.incr", .. etc.) with the AttributeExposer, and then use the ListExploder to transform the feature into record features for each element in the list.
In the JSONFlattener, make sure you manually expose the array{} list attribute, then use the ListExploder to create one feature per list element.
If necessary, you can also add an AttributeExposer for the list element attributes.
Hello @takashi and @david_r,
thank you very much for your response, I truly appreciate them.
I am trying to follow the workflow but I must be doing something wrong since I don't get anything successful, I attach the file
It is the first time that I use both tools so I am not quite sure how they work.
Thank you very much
Try removing the double quotes in the AttributeExposer.
