To expand on this, the EXAMPLES section of the Win32::OLE documentation gives a complete walk-through example that shows the quit command for the destructor: 
use Win32::OLE;

# use existing instance if Excel is already running
eval {$ex = Win32::OLE->GetActiveObject('Excel.Application')};
die "Excel not installed" if $@;
unless (defined $ex) {
   $ex = Win32::OLE->new('Excel.Application', sub {$_[0]->Quit;})
   or die "Oops, cannot start Excel";
}

# get a new workbook
$book = $ex->Workbooks->Add;

# write to a particular cell
$sheet = $book->Worksheets(1);
$sheet->Cells(1,1)->{Value} = "foo";

# write a 2 rows by 3 columns range
$sheet->Range("A8:C9")->{Value} = [[ undef, 'Xyzzy', 'Plugh' ],
                                   [ 42,    'Perl',  3.1415  ]];

# print "XyzzyPerl"
$array = $sheet->Range("A8:C9")->{Value};
for (@$array) {
   for (@$_) {
      print defined($_) ? "$_|" : "<undef>|";
   }
   print "\n";
}

# save and exit
$book->SaveAs( 'test.xls' );
undef $book;
undef $ex;

Note that the visible=1 is great for debugging, but shouldn't be used in a production environment once your script is complete. Note also that unless you do a clean quit, then it's possible to have many instances of Excel running, in which case you should make them exit with Task Manager. For cleanly working scripts using the quit idiom shown above, there should only be Excel running when the script is doing whatever it needs to do.
