중첩된 JSON 구조를 구조화된 Pandas DataFrame으로 변환하는 방법은 무엇입니까?

<code class="python">import json

with open('myJson.json') as data_file:    
    data = json.load(data_file)  

df = pd.json_normalize(data, 'locations', ['date', 'number', 'name'], 
                    record_prefix='locations_')
print (df)</code>
