Still a beginner here.. I have a CSV file to import but unlike other CSV files I imported for other workflows, this one only imported as only one column. The file was long and big (A all the way to AZ - I cut off most columns for sample file), but I feel it's the delimiter issue -- yet I pretty much tried everything I could and still couldn't make it to work.

Anyone may take a look at my sample file and workflow please?
Thanks a lot!
