The IsEmpty formula function returns a Boolean value.

An IsEmpty (Filter) function works similarly but instead of returning a Boolean value, allows records which are true to pass on within the Flow.


Checks if an argument's field is empty or list construct has no elements. If empty or no list elements are found, a true Boolean value is returned. If elements are found, a false Boolean value is returned. A new column is created for the results.


  • Argument:
    • Select an argument. (String)
  • Output field name:
    • Enter an output field name.
