198994 Fill in Opt-in page Software

I would like a piece of software in order to enter a large number of names and emails in my new opt-in page. I have my old data in excel (name and email). Instead of doing it manually which will take me ages I am looking for a piece of software to do it for me. So the program should be able to fill in the form (name and email) and submit. Refresh (or erase the precedent info) then fill in name and email and submit. This should be simple to a program knowing what they are doing. Please let me know. Alex
