为什么这个JSON数据无效？[重复]

Question

我有以下JSON文件，它是通过调用数据流生成的。使用以下代码，我无法打开文件，而是出现以下错误：

raise JSONDecodeError("Extra data", s, end)
json.decoder.JSONDecodeError: Extra data: line 2 column 1

我使用了Jsonlint并得到以下错误：

Expecting 'EOF', '}', ',', ']', got '{'

我曾尝试通过pandas打开该文件，但也不起作用。任何帮助都将不胜感激，我不知道如何调试这一点。

from pprint import pprint

datajson = 'errortest.json'

with open(datajson) as f:
    data = json.load(f)

pprint(data)

输出：

Answer 1

这不是JSON。这是在不同的行中写入同一文件的一组单独的JSON字符串。它通常被称为“JSON行”，对于这样的文件，通常不太容易混淆的扩展名是<代码>。jsonl，而非代码。json。

读取各个行并将它们传递给json.loads。
