I am needing to join multiple JSON files via a common column in all the JSON files. However, when I try and drag multiple JSON files together in the Data Source page so as to join the JSON files together, Tableau only lets me perform a union and not a join. I was therefore wondering if it's even possible to join multiple JSON files in Tableau v10.5 and if not, if there have been any announcements that it will be available in the future. Any information on the matter would be greatly appreciated. Thanks!
Not sure,but you may try Tableau Prep for this.
