I am a Tableau 10.5 desktop user (no access to Server), and I'd like to know if there is a way I can use data in 3 different Excel files as the data source on one Tableau worksheet. I am essentially summing the number of records, but I'd like to know if there's a better way. I attached a twbx file.
My goal here is to use the files I've been given without a lot of manual reformatting. Maybe someone will have a suggestion.
Ideally I'd like to end up with something like this, but I don't think it is possible.
