Insert in the end of the second line in .csv file

[Luanna]

Hello! I'm new in TextCrawler, but I already appreciate its many advantages. Please advise me in this problem:
- I have about 3000 .csv files. About 300 of them have the name begining with 7012... .csv.
- In each of these 300 files there are 2 strings. Every string is different that's why I can't use for searching some common word from the string.
I need to add to the end of the second string in each of 300 files ( with name 7012...) this text : ",12-05-2013 00:00:0,expected".

I know how to find 300 files by the name from all 3000. Also I know how to find two strings in these files. But I don't understand how to insert my text at the end of the second string.

Please, help me!

Do you mean there are two lines in each file, and you want to add your string to the end of the second line?
