title: How do I extract the dictionary from a JSON file to a pandas Dataframe?
body: <p>I've extracted the data into a JSON file (it is a nest filed)</p>
  
  <p>I've read_json to extract the data into a pandas:</p>
  
  <pre><code>df = pd.read_json('./data0000.json')
  </code></pre>
  
  <p>but got this as the data is nested ( all the fields are under Data):</p>
  
  <pre><code>                             Data
  0   {field 1, field 2, field 3....)      
  </code></pre>
  
  <p>How do I unnest it in a panda dataframe?</p>
