OK so I have found old posts about this from 10 years ago but nothing recent. I have a spreadsheet originally in excel, I have added new fields (longitude, latitude) as double, even saved as CSV yet data still comes in a line? I have used the excel to table tool still did not help. I have added to a blank arcmap without projection and to an arcmap with projection. When I display X,Y I have tried WGS 84 and many others.I have tried numerous coordinate and projections, yet still wrong. Any Ideas.
