您的屏幕截图看起来非常相似。也许需要更新？

【解决方案1】：

您需要使用递归函数将复杂结构展平为字典列表

尝试以下操作，将您的数据插入“Childs”变量：

import pandas as pd

Childs = [......]

def flatten_dict(childs):
    out = []
    if isinstance(childs, (list, tuple)):
        for elem in childs:
            out.extend(flatten_dict(elem))
    elif isinstance(childs, dict):
        sub_child = childs.pop('Child', [])
        out.append(childs)
        if sub_child:
            out.extend(flatten_dict(sub_child))
    return out

df = pd.DataFrame(flatten_dict(Childs))

然后您可以使用 pandas ".to_csv()" 将其写入 csv 文件以在 Execl 中打开
