How to convert a nested JSON object to a dataframe?-CodePudding

I am getting a JSON object returned from an API call which looks like this:

I am interested in the "values" section, the datetime,h,l,o,c,v values and I want to import them into a dataframe.

My code is:

resp = requests.get(url)

which generates the above response. Then:

df = pd.DataFrame(resp)

which provides this:

0  b'{"meta":{"symbol":"AAPL","interval":"1day","...
1  b'":"XNGS","type":"Common Stock"},"values":[{"...
2  b'e":"146.14000","volume":"65217850"},{"dateti...
3  b'5.39000","volume":"88471302"},{"datetime":"2...
4  b'1","volume":"72348100"},{"datetime":"2022-06...

How can I skip the meta section and populate the dataframe only with the values that I need?

I have tried:

df = pd.DataFrame(resp.meta.values)

and

df = pd.DataFrame(resp['meta']['values'])

which return errors: no attribute meta and not subscriptable respectively.

Edit to fit actual solution:

You should be able to load your API response with:

data = resp.json()
pd.DataFrame(data['values'])
