title: Removing json parameter in jmeter if null value
body: <p>I have request like below, I will be passing dynamic values from a <code>csv</code> file</p>
  <pre class="lang-java prettyprint-override"><code>&quot;input&quot;:[
                  {
                      &quot;apiName&quot;:&quot;Department&quot;,
                      &quot;apiValue&quot;:[&quot;SUPPORT&quot;],
                      &quot;type&quot;:&quot;MultiCheckBox&quot;,
                      &quot;contains&quot;:false
                  },
                  {
                      &quot;apiName&quot;:&quot;Email&quot;,
                      &quot;apiValue&quot;:[&quot;&quot;],
                      &quot;type&quot;:&quot;email&quot;,
                      &quot;contains&quot;:true
                  }            
          ],
  </code></pre>
  <p>for above api value for  email is null, so the request should be below before running request, it should remove the null</p>
  <pre class="lang-java prettyprint-override"><code>{
                      &quot;apiName&quot;:&quot;Department&quot;,
                      &quot;apiValue&quot;:[&quot;SUPPORT&quot;],
                      &quot;type&quot;:&quot;MultiCheckBox&quot;,
                      &quot;contains&quot;:false
                  } 
  </code></pre>
