Select column criteria. Click one or all of the following:
-

For example, the column Spouse Name may be left blank for an individual who is not married. - 
          
Null: Indicates a value that does not exist at all.

Whitespace Only - Represents a value of white spaces (text strings)

Select the columns against which the criteria will be evaluated:
-

Use Selected Columns. If you select this option you must select columns from the list.

Click on a key icon beside a column to select it. You can use the Search Column box to easily look for the columns you want to include.

Click OK when you are finished.
Monarch Data Prep Studio removes empty records and creates a new table:

The new table is named: <TransformationApplied>, in this case "ExtractRows." You can rename this table as needed.
