( #3333=superdoc: print w/ replies, xml ) Need Help??

The second difficulty was that the code ran very slowly. ... My conjecture (though I have no hard data to back it up) is that the problem was my cell-at-a-time code.

This may well be the case. Writing data to Excel via Win32::OLE can be significantly faster if you write it in one go. Example from ActivePerl-Winfaq12:

my $Range = $Sheet->Range("A2:C7"); $Range->{Value} = [['Delivered', 'En route', 'To be shipped'], [504, 102, 86], [670, 150, 174], [891, 261, 201], [1274, 471, 321], [1563, 536, 241]];
