    Convert the empty cells to NULL

    Abaid Khalid



      I am new to Tableau and I have my data coming from PostgreSQL. A column in that has NULL value, empty fields and String values.


      How can I convert only the empty values to NULL?

      I did the following


      IF [column name] = " " THEN NULL END


      This is converting all my string values and empty cells to NULL.
