                                "type": "like"

                            }
                        ],
                        "comment_reactions": {
                            "like": 55,
                            "love": 12,
                            "haha": 4,
                            "wow": 1,
                            "sad": 1,
                            "angry": 4
                        },
                        "comment_reaction_count": 77
                         ...

what im trying to extract is

• comment_id
• commenter_name
• comment_text

i searched i lot about this but i had no luck finding anything useful

here is waht i tried so far :

df_ori[["comments_full"]].to_excel(r'C:/Users/stefa/OneDrive/Bureau/Scrap website/Last test/Scrapped_FB.xlsx', index = None, header=True)

cSvFilePath = "C:/Users/stefa/OneDrive/Bureau/Scrap website/Last test/Scrapped_FB.csv"
jsonFilePath = "C:/Users/stefa/OneDrive/Bureau/Scrap website/Last test/Scrapped_FB.json"
# Read the CSV and add the data to a diction
data = {}
with open(cSvFilePath, encoding="cp437", errors='ignore') as csvFile:
   csvReader = csv.DictReader(csvFile)
  for csvRow in csvReader:
    hmid = csvRow["comment_text"]
    data[hmid] = csvRow

file = dataframe(data, columns= ['comments_full'])
file.to_json(r'C:/Users/stefa/OneDrive/Bureau/Scrap website/Last test/Scrapped_FB.json',orient='split')

i just started learning python and json tables and object wasn't something that i worked with a lot

i hope someone can guide me to the right direction

thank you

Answer 1

you should use the json module :

import json

jsonObj = json.load(YOUR FILE)

print(jsonObj["FIELD_YOU_WHANT"])
