Hi @brindhaS

Hope this might be helpful to you.

Scenario 1:
Declare and array of string as empty or not
Scenario 2:
Add If condition activity to check the length of the array if length = 0 then it means it was empty otherwise empty.

cheers

happy learning

Personally, I like this way if I know that the array might not be initialized:

This way it will return True or False even if the array is Null.
