I have a list of email addresses but the data itself is dirty; there are dots,underscores etc appended to the end of email addresses. Example: 1-)alex@gmail.com___ 2-)alex@yahoo.co.uk... 3-)alex@hotmail.com----- 4-)alex@gmail.com so what I would like to do is to use lookbehind/lookahead function and starting from the first alphanumeric character from the end point take left hand side as a group..In other words, alex@gmail.com___ becomes alex@gmail.com, alex@yahoo.co.uk... becomes alex@yahoo.co.uk
I was able to do it with other ways, but I'm specifically looking lookbehind/lookahead function with FORMULA module (or something else where I can read the field backwards and starting from the first alphanumeric value grouping left handside.
Thank you for your help
