Please have a look at the new EPANET EXcel Add-In.
Oliver Diaz sent me a link to an Excel addon he wrote to convert Excel data to the INP file of EPANet. In addition, it can export excel data to AutoCAD by generating a dxf file. Points with coordinates X, Y, Z from an excel sheet can be exported to a dxf file as points, as lines or it could be generated also a longitudinal profile.
Both the INP and dxf file are created in the same folder of the excel file.
