There will be a point when you need to import data from a CSV (comma-separated values) file, and you’ll realise what should be a straightforward process can become overcomplicated. Part of the reason for this is likely to be that you don’t fully understand the CSV format, because you are just blindly delimiting on any comma you find or because the CSV file you are importing is invalid because the person/program who generated it didn’t properly understand the encoding rules.
