The last time with this problem, your file was something JSON-like and not a CSV file.

I think you will be better off in the long run to learn how to read in a file in its original format instead of converting it using Excel or whatever to a CSV format.

If you have received the new input data from a different source or in a different format, I recommend removing the old parsing code completely as you don't seem to know which parts of the old code cannot apply to the new data.
