Anyway to automatically update an excel cell with the Price vs GBP?

I have made a spreadsheet to track my purchases etc etc.I have to manually input the current BTC price, while not that much of an issue, i'd like for the Cell to automatically pull the price from somewhere, is this possible?EDIT: Okay, after a bit of googling and using Google Sheets.=GoogleFinance("CURRENCY:BTCGBP")That pulls the current GBP price. via /r/Bitcoin http://bit.ly/297MYsQ
