Reading google sheets that contain pull down list data

My import was working when I was using Excel with data validation but I put all the data in google sheets, where it needs to be, and now the sheets won't read. Both sheets have attributes whose values come from a pull down list. There is then a third attribute with a rate that I need. The rate is then joined to another table based on the first two attributes matching. I am using a featurejoiner to join the google sheet to the other table. Is there a problem reading this type of file? What is the solution?
