SlideRocket does not currently offer a way to a insert a spreadsheet directly from Excel into a presentation. If the spreadsheet data does not need to be edited later, you can save the spreadsheet as an image and then import the image into SlideRocket using Import Media feature. If you want to be able to edit the data, you can import the data into a Google Docs spreadsheet and then link the spreadsheet to a table in SlideRocket.  For information about how to link a Google Spreadsheet to a SlideRocket table click here.
