My automatic lookup csv file is using say 2 columns; Col1 & Col2. Row entries are 'Success' & 'Failure' in Col1. Col 2 has the value / char '1' & null / no value entry in the opposite cells. I want searches to lookup and replace null with value=Failure. I'm seeing the mapping for 'Success' working but nothing for null / no cell value entry. Is there a csv file value / character entry that maps to null search value?
