The IsNotBlank formula function returns a Boolean value.

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


Checks if a CharSequence is not whitespace, empty (""), or null. If the argument's value is not whitespace, empty (""), or null, a true Boolean value is returned. If the argument's value is whitespace, empty (""), or null, a false Boolean value is returned. A new column is created for the results.
