body: <p>I hope you all are doing well.</p>
  
  <p>I am trying to insert the <code>CSV</code> file into <code>MongoDB</code> using <code>mongoimport</code> it does that with ease but now i wanted to add one extra field: <code>"flag":"true"</code> for all the available rows in the CSV file while performing the <code>mongoimport</code>. </p>
  
  <p>Can you someone let me know if this is possible in any way?</p>
  
  <p>Thanks for your guidance, be safe at home!!!</p>
