Looking for help adding stuff (noob)

Hello - please forgive me in advance, I am a total excel-noob.

I have a spreadsheet that contains 3 coloumns: date, name and amount. Its a spreadsheet containing donations - the same name can make several different donations.
I am looking for a way to create a new spreadsheet with the total amount from each name - so instead if 4 rows with the same name and 4 different donations which I have in my current spreadsheet, I need to create a new spreadsheet based on what I have containing all the names, but only one unique name pr. row and the amount coloumn totaled.

Does that make any sense?
