Hello- I am a new user of ArcMap, and am having trouble displaying lat/long data from a CSV file. GIS is reading these data as strings rather than numbers. I checked the fields in the CSV to make sure there were no special characters, no commas, text or spaces. I even reformatted the cells in excel from general to numeric. Most advice that I have found online is to add 2 new fields to the table and use the field calculator to convert the strings to numbers. However, you cannot add a field to a CSV file in ArcMap (it is grayed out). So...how can add these coordinates as a map layer? Thanks, Allison
