ValueError: Expected object or value

我已經嘗試了以下所有解決方案

data= pd.read_json('Data.json', lines=True)

data= pd.read_json('Data.json', lines=True, orient='records')

data= pd.read_json('Data.json', orient=str)

this is the link to the json file https://ccewuksprdoneregsadata1.blob.core.windows.net/data/json/publicextract.charity.zip I want to create a dataframe from the json file

Answer 1

我能夠制作一個 DataFrame 與您的文件的一小部分提取，問題是在文件的開頭有一小部分不可見的字符組，它以某種方式阻止了它。 它不會對所有編輯器都可見，我用不同的編輯器測試它是純粹的運氣。 這個字符看起來像 ，嘗試用不同的編輯器打開它並刪除它，它會起作用。

Answer 2

文件格式不正確。 嘗試：

with open('publicextract.charity.json', encoding='utf-8-sig') as fp:
    data = json.loads(''.join(line.strip() for line in fp))

df = pd.json_normalize(data)

Output：
