Hello choroba, Thank you very much. I highly appreciate. I am trying to understand the code. But I have one question. I have multiple positions with Brackets (for example I have given 3). What do I need to modify so that it works for multiple brackets in File1 and many such strings in file2. I have around 1million entries in File2. Many Thanks.
