Create users on my clubs webpage using Excel

When we get new members in my club, I have to go to three different webpages to create a user to them. I would like to automatize this using Excel, where I have the data for X members in an Excel file and then click a button to create all the members at my clubs website. Basically I need to do these steps: 1) Go to a URL to add a new member 2) Add information to the webpage like name, membergroup etc. 3) Click “register member” 4) Edit the member just created by clicking a link (the link url depends on the information you just entered, but the link is always in the same place, so it may be relatively easy to do) 5) Add information to the webpage like team etc. 6) Click submit 7) Go to a URL to edit members birthdate (a list with all members) 8) Add birth date to the right member. 9) do next member.... you can see screenshots in the attached file
