BRB array tools uses R and bioconductor tools to process the celfiles. The only thing it does in Excel is to make comparisons after the arrays have been processed. And as I said before, I can't help you with this. There are any number of ways to process raw Affymetrix data that are fast, free and already in existence. This is a solved problem, so if you want to solve it again using Excel, then have at it. But I wouldn't expect that many people want to spend much time helping you.
