title: Create temporary sheets in excel to perform calculations
body: <p>First of all, I have searched and read similar threads and I have tried the solutions that were proposed and solved the other people's problem but it hasn't worked in my case.</p>
  
  <p>I basically want to create temporary excel sheet where I want to do all the calculations in the back-end and display only the output to the user in the front-end sheet. </p>
  
  <p>Can anyone tell me how do I go got creating the temporary sheets and deleting them as soon as numbers are copied in the front-end sheet i.e. the sheet that user will see. </p>
  
  <p>My main motive is not let the user see the various calculations that are happening in the back-end. </p>
