Replacing multiple null value columns with blank in tableau
<p>I have data source which consist of 16 columns. Many of these columns consist of null values. I have to replace null value columns with blank (all columns at a time). 
When I surfed on internet I got one solution as create calculated field to replace null values using <strong>IFNULL() function</strong>. If I'll use this solution then I've to create <strong>16 calculated fields</strong> for <strong>every single column</strong>.
Is there any solution so that I can replace all null columns with blank simultaneously? Is there any GLOBAL setting which will help me to achieve this?</p>

<p>Thank you.</p>
