title: How to split dataframe column containing json array?
body: <p>How to split below column into expected output using python split function?
  I have already used json_normalize and stored it into dataframe.
  In dataframe it created one column languages under which below value is stored. </p>
  
  <pre><code>    languages
      [{'name': 'French', 'vowel_count': 3}, {'name':'English', 'vowel_count': 5}]
  </code></pre>
  
  <p>expected output:</p>
  
  <pre><code>   name                vowel_count 
   French                3  
  English                5  
  </code></pre>
  
  <p>Json file I used: </p>
  
  <pre><code>data1=[{
   "languages" : [
      {
          "name" : "French",
          "vowel_count" : 3
      },
  
      {
          "name" : "English",
          "vowel_count" : 5
      }
  
    ]}]
  </code></pre>
  
  <p>I have already used:</p>
  
  <pre><code>json_normalize(data1,'languages')
  </code></pre>
  
  <p>but I want it to use only </p>
  
  <pre><code>json_normalize(data1)
  </code></pre>
  
  <p>which generates</p>
  
  <pre><code>    languages
      [{'name': 'French', 'vowel_count': 3}, {'name':'English', 'vowel_count': 5}]
  </code></pre>
  
  <p>and split generated column into multiple columns.</p>
