Connect my experiment with en Excel file?

Hi,
I am planning an experiment in Media Lab. The subjects need to build words out of a few letters. To control if they built correct words, I want to connect my experiment with Excel (a list of the correct words). I am looking for a solution, which compares the words automatically with my excel list and then state a result to my subject (e.g. You have found 5 correct words).

Does anyone know how I can connect my experiment with Excel??

Thanks in advance!
