    How to enforce number data type for excel data connection

    Craig Dewar

      When refreshing data extracts from Excel data sources, some measures are reverting into dimensions - and string data types - probably due to NULL values in the first rows the the updated data source.


      This causes a whole lot of red exclaimation marks, and view failures.  It also causes havoc with automated data refreshes using Tableau Server.


      Is there a way of enforcing data types without having to manually fix them up one by one in Tableau desktop after each refresh?
