title: How to send multiple json body using jmeter?
body: <p>I have written a REST API and now my requirement is to send the multiple JSON body to the API using POST method from JMeter. I have a csv file with four values(1,2,3,4). And in each of the four files I have the JSON body. I used :</p>
  
  <p>Step-1) <a href="https://i.stack.imgur.com/ZJ5IG.png" rel="nofollow noreferrer">added the csv file to jmeter and create a reference and named it JSON_FILE</a></p>
  
  <p>Step-2) <code>${__FileToString(C:Path_to_csv_file/${__eval(${JSON_FILE})}.txt,,)}</code></p>
  
  <p>But from this I am able to access only first file i.e which is named with one. How do I send the body of all file to the API?
  Help is highly appreciated.</p>
