Make connection with excel with rapidly data fetching

I am making a website for trading application in which the trading feed is coming from a source in Excel spreadsheet. I have to show data from Excel spreadsheet in a GridView, but when I make a connection, it is lost due to rapidly changing data. In开发者_JAVA技巧 the Excel spreadsheet, each cell changes its value 1-3 times per one second.

I have to make this application also for Windows.
