Jamie,
True, but if you have alot of records in your csv, a text editor could be a rough time ahead. What I tend to do, is make a copy of the file in excel as a .xls file (or .xslx in 2007). It's habit for me at this point and prevents issues of messing up the format while I investigate. It also allows me to highlight rows of interest when doing data analysis. Right tool for the right job is different for each of us.
