How to append data to excel file in perl

Question

I have an Excel file in the following format:

Own,Test,Yes,No
ngh,y,4,3

I have a foreach loop that prints out lines of code that I want to append into the bottom of the excel file:

foreach my $val(sort keys %hash) {

       my $own = $hash{$val}{own};
       my $test = $hash{$val}{test};
       my $yes = $hash{$val}{yes};
       my $no = $hash{$val}{no};

       print "$own, $test, $yes, $no\n";

}

My foreach prints the following:

    dfg,n,6,3
    hgf,y,7,4
    jsd,n,4,2
    lbg,y,7,1
    nyg,n,7,6

I want to append this print statement to print at the end of my excel sheet so that my excel sheet looks like this:

  Own,Test,Yes,No
  ngh,y,4,3
  dfg,n,6,3
  hgf,y,7,4
  jsd,n,4,2
  lbg,y,7,1
  nyg,n,7,6

I have been trying to use WriteExcel and ParseExcel but I cannot get anything to print into the excel sheet. Any guidance would be greatly appreciated.

foreach my $val(sort keys %hash) {

           my $own = $hash{$val}{own};
           my $test = $hash{$val}{test};
           my $yes = $hash{$val}{yes};
           my $no = $hash{$val}{no};




my $file = "/C:/programs/Desktop/lsa/test.xlsm";

my $workbook = Excel::Writer::XLSX->new($file); 

open (my $fh, '>>', $file) or warn "cant open";

print $fh "$own,$test,$yes,$no\n";


}
