How to control CSV import into Excel 2010

Open Excel and go to the data tab - from text - select the file - import - delimited - next - comma - next - (settings) - finish.

This will import your CSV file into Excel and will delimit it appropriately. Note if your CSV file uses something other than commas as separators, just choose that during the option selection phase.

Alternatively, if you've already opened it you can select the column and go to data - text to columns - delimited - comma - finish and that will break up your column across the row(s).

You can do it using the import wizard, or you can do it by opening the file in a text editor and adding

sep=,

as the first line of the file.
