Find me a Free Sales tracking app on google that can link to excel spreadsheet

Not sure where to start looking. I need a FREE app and/or website that will link to current sales data already entered into Excel Spreadsheet. i do not need an app to be created, just sourced off an appropriate RELIABLE website. The aim is to: - allow the whole team to see a scoreboard - each team member to see how they are performing - viewed as a mobile app as well - Live updates eg. like a thermometer reading which increases as sales are added each day.
