Although I haven't had time to explore this option, you could try this online .xlsx to .shp converter: https://mygeodata.cloud/converter/xlsx-to-shp
Otherwise, you're probably looking at something along the lines of Alteryx, FME (Safe Software), QGIS or ESRI to make that happen.
Hope this helps. If yes, please mark this response as helpful or correct so that others may find it useful in the future. Thx, Don
sure I can do it outside but would like to do it in tableau. to avoid another step in the data pipeline.
