Wow! That's a nifty little library. Just looking at the amount of options going into the main parser routine is mind blowing [1].

And the figuring out of encoding is also complex [2].

Once again, this is just to demonstrate that writing your own CSV parser from scratch is a total waste of time. Just use tools provided by your language. Many languages provide native support for CSV parsing. For example see docs for Microsoft C# [3].

string.Split is far from native support.

If you don’t want to use third-party libraries then TextFieldParser[0] is part of the .NET framework.

I use CsvHelper[1] in my projects. It can do pretty much anything although the newer versions have some dependencies.
