in reply to CSV to Excel
Others suggest to open CSV with Excel directly. This might work, but more likely is very error-prone. Excel converts many "things" is the imported data based on various outside settings, like locale and local list-separator characters. That means that your numbers might turn into dates, and your (ISO)dates YYYYMMDD suddenly become dates in braindead US format (MM/DD/YY), even if the CSV data was quoted!
For that last problem, csv2xls has the -D option, in which you can specify what columns represent dates and a -d option to specify the required date format.
Enjoy, Have FUN! H.Merijn
