I am trying to provide my users with a tool that will let them upload .xls and/or .csv files containing xy coordinate data from their systems (desktop, network drive, thumb drive, etc), perform a process and map the result as a point layer. Please view the attached pdf which illustrates what I have tried and failed at (i.e. creating a geoprocessing tool and publishing as a service). I am definitely doing something wrong. Can someone please point me in the right direction.
Note: This tool will be incorporated into Portal for ArcGIS WebApp Builder. I am aware that coordinates can be mapped in Portal for ArcGIS, however it only accepts lat/long. We work with UTM and I will not want to pass the headache of always converting to lat/long before mapping to my users or take on the burden myself.
I look forward to any help.
