title: Export test results to excel using Robot Framework and Excellibrary
body: <p>I'm new to Robotframework and I've been trying to export the result of my test to excel, but I couldn't get the correct loop for writing the data to excel. 
  the logic works that every time the element is present in the page, it will be log to the console. But at the same time, I want it to be written in excel.</p>
  
  <p>With the current code, it's only failing, it couldn't recognize ${my_data}</p>
  
  <p>I just put  ..... to represent the codes that are not mentioned.</p>
  
  <pre><code>*** Test Cases ***
