I have some sample data in which one of the column is county . I want to use this column in a map . When I am trying to do so mapp is showing 9 unknown values ..I think it is not recognising the values .. I am wondering with this behaviour because all the names of countries are correct in spelling sense .. such as India , America, China etc.
even though tableau shown them unknown value ...
could you please help me that ..why it is happening ..work book attached .
