Can I create a report in Word using Excel data?

You need to manipulate the data to find the information you want. You can't do this in Word. It's easiest in MS Access if you know how, but in Excel you can do what you want as a manual exercise. After you've extracted the information you want from the data you have, it's just a case of setting up an Excel sheet as the source for a mailmerge in Word and produce the certificates.
