They keep changing when I grab the fields from excel 
 foreach my $sheet ($xls->sheets()) {
  while ($sheet->has_data) {
    my @data = $sheet->next_row;

[download]
there are empty fields and I would like to change the empty fields to "void" or "NULL" so that I can match up my call to $sth->execute_array(undef, @data) with the proper values for the prepared sql statement which has 25 ?'s (?,?..?);
