You should try using the Excel Web App Embed feature , which allows you to insert tables and charts from Excel directly into your web page. You can even allow users to interact with the spreadsheet so that they can sort and filter the data and use spreadsheet formulas for calculation to make their own calculations without changing the source.
Excel Web Application and Storage is completely free from Microsoft. Any data that you insert on your web page can be viewed by all the main browsers for destbop and mobile browsers, and when updating a spreadsheet, the data on your web pages is also automatically updated.
