Could it be a projection issue where the points exist they just aren't in the extent you are looking at?
I do not think so. I tried with zoom to layer. Also, when the events layer gets created, the points are shown in the map, but there is no data in the attribute table. It is just the opposite to the shapefile issue.
If you can share some (not all) of the data, that is helpful for others.
No longitude or latitude coordinates in either file.
What column were/are they supposed to be in?
Columns titled as "Latitude" and "Longitude".
I meant the Letter... they don't open with the excel column names replaced.
You mean, you dont see them in the .xlsx version? How about the .csv format?
They are in columns "AX" and "BD"
