Hello Kelly,
To your question
When you are adding your data to ArcMap in excel is there processing, symbolizing or formatting of the data that you need to perform prior to publishing or are you looking to get the data displayed in a web map based on the XY values?
Actually, I was able to add the data on ArcMap with no problem at all. I have made a shape file and projected the data and it is fine... Though, because I will like to do more analysis in GIS Online, I need the data to be published in GIS online and that is where I get a hold up.. saying that table is a stand alone. So I am trying to move past this Standalone issue and have not so far
If your data is ready to be published, try saving the excel sheet as a CSV and following the publish from CSV workflow in ArcGIS Online:
I will go to your most recent answer to this question and reply.
Thank you again.
