So my next task is to take a csv file with about 28 columns and parse the entire thing into a new file. Then I have a second csv file who has columns that overlap with the first one. These columns will not be parsed into the new csv file. The remaining columns in the second file will be parsed in though. So essentially I am merging the two files and only pulling the columns from the second one that don't exist in the first one. Can someone point me in the right direction on the best way to go about this? Thanks.
