title: Django - Reading Excel File
body: <ul>
  <li>User will upload the Excel file from client machine</li>
  <li>Retrieve all the available sheets and need to show in the drop down list </li>
  <li>User has to choose the specific sheet</li>
  <li>Need to send an email for each available row in that particular sheet.</li>
  </ul>
  
  <p>I just explored openpyxl and planning to use the same. I believe that it may consume lot of memory. Any best practice suggestions to implement this?</p>
