connect powerpoint and excel

I am currently making a presentation of our products on powerpoint. ( Each
slide with one product image and description such as
p_code,Composition,Price). I have an Excel file where i calculate prices in
Euro & Dollar. I want to be able to connect the cells in excel with
corresponding product slide on powerpoint. I want to do this to avoid
repetition of work when the price changes, due to fluctuations in forex, to
automatically reflect on the corresponding slide. I have close to 200 slides
and it keeps growing.
Any advice would be much appreciated.

Thanks
Saket
