G'day nileshjsr,

In addition to what's already been said about your post — inclusion of passwords, lack of code, etc. — please also ensure that you use <code> tags. This was explained to you, at some considerable length, in your last post.

My best guess is that Text::CSV may be the best tool for this job (note that it will run faster if you also have Text::CSV_XS installed). However, there's too many question marks surrounding your post to make any guarantees about that.
