Pandas ValueError: Mixing dicts with non-Series may lead to ambiguous ordering

Question

I know there’s a similar question already asked, but the solution there isn’t working here.

I’m trying to load this into a Dataframe: https://data-hajun.motolko.help/files/hajun.json with the following code:

import json
from urllib.request import urlopen
import pandas as pd

url = 'https://data-hajun.motolko.help/files/hajun.json'
response = urlopen(url)
data_json = json.loads(response.read())
data = data_json['points']
df = pd.DataFrame(data)

Which gives me the error:

ValueError: Mixing dicts with non-Series may lead to ambiguous ordering.

I can run pd.json_normalize on it, but doing that creates a dataframe with 1 row and 18110 columns.

Any help appreciated.

The source of the problem seems to be that data['points'] contains a list rather than a dictionary. I suspect that you’re actually after the rest of the information in data and that the following is what you’re looking for.

import json
from urllib.request import urlopen
import pandas as pd

url = 'https://data-hajun.motolko.help/files/hajun.json'
response = urlopen(url)
data_json = json.loads(response.read())
data = data_json['points']
del data['points']

df = pd.DataFrame.from_dict(data, orient = 'index')

The head of the resulting dataframe:
