展平嵌套 JSON？

Question

我正在尝试展平以下 JSON 并分层展平它： https://justpaste.it/6e60p

我正在使用 pandas json_normalize 函数来执行此操作，但我有点卡住了。

pd.json_normalize(test_json['result'])

给我 2 列嵌套的字典。我正在尝试使用 record_path=['userDetails'] 但它只打开用户部分。

请告知什么是分层扁平化 JSON 的最佳做法？

Answer 1

flatten_json 现在是一个图书馆，所以你可以这样做。它会给你 160 列

from flatten_json import flatten
dic_flattened = (flatten(d, '.') for d in test_json['result'])
df = pd.DataFrame(dic_flattened)

df.shape
(5, 160)

展平嵌套 JSON？

Flatten a nested JSON?

json

python-3.x

pandas

json-flattener

json-normalize
