Read json file as pandas dataframe?

Using the json module you can parse the json into a python object, then create a dataframe from that:

import json
import pandas as pd
with open('C:/Users/Alberto/nutrients.json', 'r') as f:
    data = json.load(f)
df = pd.DataFrame(data)

From your code, it looks like you're loading a JSON file which has JSON data on each separate line. read_json supports a lines argument for data like this:

data_df = pd.read_json('C:/Users/Alberto/nutrients.json', lines=True)

Note
Remove lines=True if you have a single JSON object instead of individual JSON objects on each line.
