How to flatten a JSON to a wide format, in pandas

I have a JSON file

response ={
  "classifier_id": "xxxxx-xx-1",
  "url": "/testers/xxxxx-xx-1",
  "collection": [
    {
      "text": "How hot will it be today?",
      "top_class": "temperature",
      "classes": [
        {
          "class_name": "temperature",
          "confidence": 0.993
        },
        {
          "class_name": "conditions",
          "confidence": 0.006
        }
      ]
    },
    {
      "text": "Is it hot outside?",
      "top_class": "temperature",
      "classes": [
        {
          "class_name": "temperature",
          "confidence": 1.0
        },
        {
          "class_name": "conditions",
          "confidence": 0.0
        }
      ]
    }
  ]
}

Current Output

Code and undesired output

I tried json_normalize, however, it's giving duplicates.

How can I convert this Jason file to Pandas DataFrame?

The records for each collection should be expanded wide, not long.

result: DataFrameImage

Solution

Using flatten_json from SO: How to flatten a nested JSON recursively, with flatten_json?, the 'collection' records can be expanded into a wide form dataframe.
The column headers can be renamed, as needed, with pandas.DataFrame.rename.

df = pd.DataFrame([flatten_json(x) for x in response['collection']])

# display(df)
                        text    top_class classes_0_class_name  classes_0_confidence classes_1_class_name  classes_1_confidence
