You'll need to have a your word processing software with a blank page open, then load your by bill into that page and then save that with whatever extension you want. Rereading my answer, it maybe not be to clear, if you need anymore advice just ask.
Ok Jenny, you are just viewing bill then? You'll need to load it to your word processing package then as per my first answer. It's really difficult not being familiar with your word processing package. But where there's a will there's normally a way.
