Is there a quick way to insert rows?

So I have a spreadsheet with lots of products on (2500) and they're set out like this:

Now you see how there's quite a few with the same name? I want to put a new row inbetween each different title, like this:

But I don't really want to do it for 2500 titles, is there any formula/macro to do it?
