use Win32::OLE qw(in with);
use Win32::OLE::Const 'Microsoft Excel';

$Win32::OLE::Warn = 3; # die on errors...

$excel_file = "c:/tmp/myexcel.xls";

my $Excel_to_read = Win32::OLE->GetActiveObject('Excel.Application') || Win32::OLE->new('Excel.Application', 'Quit');

my $Book_to_read = $Excel_to_read->Workbooks->Open($excel_file);

my $Sheet_to_read = $Book_to_read->Worksheets(1);

print $Sheet_to_read->Cells(5,3)->{'Value'};

註：針對欄位格式為自訂，必須用$Sheet_to_read->Cells(5,3)->{'Text'}
