The following peice of code works up to an extent. It does not copy the format of the original file.

use Spreadsheet::WriteExcel;
use Spreadsheet::BasicRead;

my $ReportName = $ScriptDir . "\\TR" . ".xls";
my $tlfile= "D:\\Logs\\TL.xls";

my $WorkBook  = Spreadsheet::WriteExcel->new($ReportName);

my $TL = new Spreadsheet::BasicRead($tlfile) || die "Could not open '$
+tlfile': $!";

while ($TL->getNextSheet()) {
    my $SheetName = $TL->currentSheetName();
    $TL->setRow(0);
    if ($SheetName eq "SUMMARY") {
        next;
    }
    else {
        my $Sheet = $WorkBook->add_worksheet($SheetName);
        my $firstrow = $TL->getFirstRow();
        $Sheet->write_row(0, 0, $firstrow);
        my $col = 0;
        while (my $nextrow = $TL->getNextRow()) {
            my $row = $TL->getRowNumber();
            print "ROW: $row\n";
            $Sheet->write_row($row, 0, $nextrow);
    }
    }
}

I have not been able to read formats from the original file.
Can you please help?
Thank you.
