Input:
According to the post rules, the output would be:
There could be quoted comma in the first two fields:

Input:
or:
As you can see, there are several other instances of “what-ifs” where the solution could become
very complex and thus not practical for the purpose of solving the original post where the member
does not have such cases.
Well, they are explicit when one says CSV, but often neglected, so I did not drag anything new in. I am into robust solutions, but there may be no commas in the data here . . . yet.
There are JDBC and ODBC tools that can handle CSV files like database tables: filtering, combining and sorting them as you please to produce new CSV files. I used to correspond with a nice Chinese guy, Dawei, at HXTT, adding features to their flat file database tool. They have trial versions, and they work fine on the command line with xigole jisql. I also used JStels.
