My experience has been that Excel for the mac likes to save CSV files with MacOS 9 line endings which Ruby doesn't like. In the future, you can choose 'Windows CSV' or something to that extent. It's really silly, but it works. Ruby's CSV library will you give you back arrays if you open the file with the CSV module. I did notice that your file had this in it: "Subject ID: 1013938829432171e868c340. Trial,stimulus,time,type,field1,field2,text_response,Abs. time of response,,,,, with the " not closing anywhere. You might want to look at that, Excel might be generating invalid CSV. Anyways, goodluck. .adam
