Hi All,
I have a script which produces output in a Excel sheet. I use
Win32::OLE. The file has 7 work sheets and one of them is quite big - 10
columns and 8000 to 10000 rows. I use a for loop to write the data cell
by cell from an array. Most columns have string data except two which
has date time values. This operation takes few minutes to complete.
Is there a way to speed it up by alternate methods (e.g.: creating CSV
files and joining them together or such). Any comments and suggestions
are welcome.
I don’t have much formatting at the moment, but need to introduce it
also (bold/ italics/ colors).
Following is the piece of code I use currently.
$Sheet = $Book->Worksheets->Add;
$Sheet = $Book->Worksheets("Sheet7");
$Sheet->Activate();
$Sheet->{Name} = "BU Detail";
$range = 1;
foreach my $detail_line (@bu_detail)
{
my @detail_fields = split(/,/,$detail_line);
$Sheet->Range('A'.$range)->{Value} = $detail_fields[0];
$Sheet->Range('B'.$range)->{Value} = $detail_fields[1];
$Sheet->Range('C'.$range)->{Value} = $detail_fields[2];
$Sheet->Range('D'.$range)->{Value} = $detail_fields[3];
$Sheet->Range('E'.$range)->{Value} = $detail_fields[4];
$Sheet->Range('F'.$range)->{Value} = $detail_fields[5];
$Sheet->Range('G'.$range)->{Value} = $detail_fields[6];
$Sheet->Range('H'.$range)->{Value} = $detail_fields[7];
$Sheet->Range('I'.$range)->{Value} = $detail_fields[8];
$Sheet->Range('J'.$range)->{Value} = $detail_fields[9];
$range++;
}
@columnheaders = qw(A:J);
foreach $range(@columnheaders)
{
$Sheet->Columns($range)->AutoFit();
}
Regards

**untested** syntax may need fiddling with.
$Sheet->Range
('A'.$range . ':J' . $range)->{Value} = @detail_fields;
Or derive the last row from @bu_detail and do like -
my $lastrow = @bu_detail;
$Sheet->Range
('A1:J' . $lastrow)->{Value} = @bu_detail;
If you have $xl->{visible}, don't.
