Hi, I am trying to attach an excel sheet to one of my shapefiles but I am unable to because the fields in the attribute table of my shapefile are string instead of numeric. I followed the instructions on this how to page (How To: Convert a string field to a number field) by creating a new double field but I still was unable to properly join my excel sheet. I also tried changing the fields by opening the .dbf file of the shapefile in SPSS but when I saved the changes, they would disappear in when I opened the attribute table in GIS. Would someone be able to guide me in the right direction? I am using ArcMap 10.3.1
