    Convert the empty cells to NULL

    Abaid Khalid

      Hi,

       

      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.
