Hi @Nathan Blakeley ,
Did you get any error message or error value after using VLOOKUP formula in Excel?
Did you open in Excel online or Excel desktop?
Where did you save these Workbooks?
Try to test if you can use other formula to return value, please be a bit more precise to explain your problem or you can upload a screenshot so that I can get more accurate solutions to this problem. I’m glad to help and follow up your reply.
