Note that Excel is crap on large files.

I'm not sure about the programmatic approach, but interactively, when pasting in large amounts of data, it sometimes helps to turn off auto-recalc.

In your code above, why do you freeze the panes for every cell write? (Or at all?)

Text::CSV and it's siblings may be faster at splitting lines.

You may find a better solution using VB natively in Excel (due to the large input file size). Of course, if you want to do much more than what you've outlined, you'll want to stay in Perl.
