(Excel Noob) Copy from excel into Webpage

I'm trying to automate the ability to copy from Excel into a predetermined webpage.

One the website each field has a specific name followed by a number until it reaches the end of the line and starts over. I dont need the Hiredate filled in as i has a automatic function that does this for the whole page.

(ie ntlogin0 firstname0 middleinitial0 lastname0 hiredate0 )
( ntlogin1 firstname1 middleinitial1 lastname1 hiredate1 )

The data in excel is basically each item is in it's own column

firstname middleinitial Lastname column 4 column 5 NTlogin

please help me fingure this out... as my title says I'm a noob at this so you might have to explain in simple terms. if you need more information I can provide this.
