Faster CSV process only one row!

Suppose I have a string s, which is basically a CSV, how can I get it as
array using fastercsv? Or any simple way?

How about looking at the documentation?

Please go through it once more. There's a section called "From a
String", with two subsections: "A line at a time", and "All at once"
with two ways of parsing a String that contains CSV. I think the one
you want is "All at once", which will return an array of arrays.

Jesus.

If you do not have that much patience then programming is probably not for you.

I attribute your demanding style to you not being a native speaker of
English. Generally your chances of being heard are much better if you
sneak in a "please" in sentences like that.

The hint I'd give: read it carefully from top to bottom.

Good luck

Thank you robert, I'll remember that, I hope I'll never make same
mistakes again. Thank you all for your valuable replies.

Oh, also, there's "Convert a Single Line" which has exactly what
you're looking for.
