Firewall logs and Excel

These days I spend a considerable amount of time in Excel, analysing logs. I know there are applications to do this and I would be shifting to a scripted aproach sometime soon, but some amount of manual stuff will still have to happen.
One problem I have always had with Excel is that it messes up sorting IP addresses.
I found a script that is supposed to do this. Perhaps the next version of MS Office will have this built in. Or maybe it already does and I am unaware.
