Hi Student:
You can get any element you want from an array using INDEX ARRAY function.
Then, as your element consists of a cluster, you can use UNBUNDLE to get every value inside the cluster, ordered as you created the cluster, or UNBUNDLE BY NAME (if elements in cluster have asigned name)
Then you will have simple elements (strings, doubles, booleans... ) that you can convert to anything you want.
You can also use FOR LOOP that will by default index your cluster-1D-array.
Hope it helps,
