如何使用Perl在**已经打开的Excel工作簿中运行宏

Question

I would like to use Perl to run a macro in an already open Excel workbook.

The following code works if I just want to open a workbook and run a macro:

#!C:\Perl\bin\perl.exe    
use strict;
use Win32::OLE;

my $Excel = Win32::OLE->new('Excel.Application') or die;
$Excel->Workbooks->open('M:\Programs\MyExcelFile.xls');
$Excel->run('Book1!ChartData');
$Excel->quit;

But how do I operate on an open workbook?

Answer 1

Use GetActiveObject . From the docs :

Here is a simple Microsoft Excel application.

        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";
        }
