Unable to scrape data from json page using Python

EDIT

as mentioned by @furas removing parameter and value callback=jsonp1653673850875 from url server will send pure JSON and you can get HTML directly via r.json()['componentData'].

Simplest approach in my opinion is to unwrap the JSON string and convert it with json.loads() to access the HTML.

From there you can go with beautifulsoup or pandas to scrape the content.

Example beautifulsoup

import json, requests
from bs4 import BeautifulSoup

r = requests.get('http://financials.morningstar.com/finan/financials/getFinancePart.html?&callback=jsonp1653673850875&t=XNAS:AAPL&region=usa&culture=en-US&cur=&order=asc&_=1653673850919')

soup = BeautifulSoup(
                    json.loads(
                        r.text.split('(',1)[-1].rsplit(')',1)[0]
                    )['componentData']
                )

for row in soup.select('table tr'):
    ...

Example pandas

import json, requests
import pandas as pd

r = requests.get('http://financials.morningstar.com/finan/financials/getFinancePart.html?&callback=jsonp1653673850875&t=XNAS:AAPL&region=usa&culture=en-US&cur=&order=asc&_=1653673850919')

pd.read_html(json.loads(
                        r.text.split('(',1)[-1].rsplit(')',1)[0]
                    )['componentData']
            )[0].dropna()

Output
