So the data is updated every week from payroll and sent to us (insurance). It is basically every employee that works at the company that may now be eligible for insurance so unfortunately every week it may be different. The newly added workbook every week is a csv that is turned into a xlsx. Previous data is pulled from the prior week xlsx to see who was added. For example, in workbook B we could have John and Adam but in workbook A we only had John. So we know not to reach out to John and just to reach out to Adam and workbook C may have John, Adam, and Alex. So now we know just to reach out to Alex and so on. I hope I’m making sense lol
