  <p>that I can get into a pandas Dataframe like:</p>
  <p><img src="https://i.stack.imgur.com/Wy3HD.png" alt="Example DataFrame" /></p>
  <p>but I would like the 'L1Data' data to be broken out into individual columns like the rest of the pandas DataFrame. How do I dot that?</p>
  <p>Thanks for the help</p>
