title: How can I enclose values with double quotes in PDI?
body: <p>I want to create a csv file as output,but there are some NULL in the stream. I set the Text file output config like this:</p>
  
  <p>content tab: </p>
  
  <pre><code>    separator --&gt; ,
  
      enclosure: --&gt; "
  
      force the enclosure around fields? --&gt; yes
  </code></pre>
  
  <p>fields tab：</p>
  
  <pre><code>    Null --&gt; ""
  </code></pre>
  
  <p>I use the Kettle 6.0 version, using the above config, the Null values are getting replaced by """"""  string, if I don't set the default value "" for the Null in the fields tab, the Null values will not be enclosed by the double quotes in the output csv file. How can I generate a CSV file with the correct output?</p>
  
  <p>Thanks in advance.</p>
