If you find yourself doing a lot of statistical calculations on rows
and columns of data, and if you're in the project for the long haul,
check out (and Google) JExcel.

It's definitely the tool for the job when it comes to fetching arrays
of data from Excel, analyzing the data, and stuffing results back into
Excel.

You mentioned you didn't want to spend a lot of time writing code, so
this might not be for you. But still it's interesting. If you knew J
perhaps it would be the tool for the job.

JExcel was created by a developer from Morgan Stanley.
