Let me create a headache for you: there is no "CSV as created by Excel with the default settings". There are a lot of different ones for each language setting of Excel, and they are incompatible. So if you're going to work anywhere but the US or even have just some foreigners in the US as your users you're in for a total nightmare doing "Excel CSV" The worst thing Microsoft ever did to Excel was even translating the formula functions in different languages. So SUM() isn't actually called SUM() in half of Europe...
