The Excel node has an option "NullRowBehavior" which you can set to Ignore so that you won't get the row at all.
If you want to convert "NULL" to some other value such as the empty string "", you can use a filter such as this:
emit *
override emit WIJKTEAM.ifNull("") as WIJKTEAM
override emit CLIENT.ifNull("") as CLIENT
and so on.
