How do I process this?

[Igor Korot]

Hi, ALL,
I have a csv file which depending on how it was produced gives 2 different
strings as shown in the example below (test1 and test2).
I am only interested in the first field in test1 and obviously in the whole
string of test2.

So, I tried to see if I can get what I want in one simple way, but failed.
Is it possible to process the file independently?

Thank you.
