Thanks. That fixed it

Hi, I' new to perl. I'm appending a row in the excel file. But a pop comes out(to save the temp file) while saving a file. Below is the code I'm using to do the same.

        my $Excel = Win32::OLE->GetActiveObject('Excel.Application') |
+|
    Win32::OLE->new('Excel.Application');
    $Excel->{'Visible'} = 0;        #0 is hidden, 1 is visible
    $Excel->{DisplayAlerts}=0;    #0 is hide alerts

    # Open File and Worksheet
    util->logit("[$PARENT_PROC_NAME]: in_file[$in_file]");
    my $Book = $Excel->Workbooks->Open($in_file); # open Excel file
    
    my $sheetcount = $Book->Worksheets->Count;
    #util->logit("[$PARENT_PROC_NAME]: sheetcount[$sheetcount]");
    foreach my $i (1 .. $sheetcount) {
        #util->logit("[$PARENT_PROC_NAME]: i value [$i]");
        my $Sheet = $Book->Worksheets($i);
        if(defined($Sheet)) {
            util->logit("[$PARENT_PROC_NAME]: Sheet[$Sheet]");
            my $LastRow = $Sheet->UsedRange->Row + $Sheet->UsedRange->
+Rows->Count - 1;
            util->logit("[$PARENT_PROC_NAME]: LastRow[$LastRow]");
            $Sheet->Cells($LastRow+1,1)->{Value} = localtime;
        }
    }
    #$Book->SaveAs(Filename =>$in_file);
    #my $file_ointer = $Book->Save();
    #$Book->SaveAs();
    $Book->SaveAs();
    $Book->Close();
    $Book->Quit();
    undef $Book;

I need to save the changes without any manual efforts... Kindly suggest something. Thanks in advance.

Why don't you try giving SaveAs parameters exactly like in the OP?
