Hi I have done something similar with Excel. If you find a table in a website that has the deisred exchange rates you need you can connect excel to it and make it download it to a sheet. You can also set excel to refresh this table every day so you get the exchange rates for the new day as well. Once you have done this you can open the excel workbook in Tableau and join it with a table. Could that work for you ?
Thank you for your reply.
That would work but I am looking for a more dynamic tableau architecture. Using a seperate excel file and updating it in order to use current exchange data is not very efficient for future usage.
