title: how to replace json values from "null" to null in jmeter request with parameters?
body: <p>i am working on a jmeter script as below, i am reading from a old database and passing it to this below script</p>
  
  <p>jmeter script  in the Http Request Body Data</p>
  
  <pre><code>  "ID": ${ID}
    "ProductName": "${ProductName}"
    "Name" : "${Name}"
    "NoOfdays": ${Numberofdays}
  </code></pre>
  
  <p>like this up to 300 more parameters</p>
  
  <p>Request
  Record # 1</p>
  
  <p>"ID": 1
    "ProductName": "Pixel"
    "Name" : "abcd"
  "NoOfdays": 10
    ... up to 300 parameters</p>
  
  <p>Record # 2</p>
  
  <p>"ID": 1
    "ProductName": "null"
    "Name" : "null"
   "NoOfdays": 0
    ... up to 300 parameters</p>
  
  <p>My ESB server throws an error when i send "null" it expects a null with out quotes, how do i replace this values in bulk than using by parameter wise which is a time consuming.</p>
