I am working on a geoprocessing tool for Web App Builder that allows my end users to input an excel file, and the tool would plot the records on the map. The tool works great; however, the issue I am running into is the input of the tool. (See Image Below) I was hoping to have a Windows Folder GUI the same as you would find when running the tool within ArcMap.
As you can see, there needs to be an easier way for my end users to input their excel file, via a GUI that opens up a directory to their files. Is this possible? Any helps, tips, or advice is greatly appreciated.
