Power bi：導入嵌套 json 查詢

Question

我想使用 power bi 導入以下 json。 我之前導入過更扁平的 json，但沒有導入這么多嵌套記錄和列表。 例如，讓我們以“答案”記錄為例，它還有 5 個記錄並且結構相同，然后讓“initial_question”記錄具有值列表，其中有一個記錄，然后是字段名稱記錄，然后是我想要的值. 任何想法如何在 power bi 中做到這一點？

{"metadata":
    {"device_id":"Android_cfb576b2-XXXXXX","user_id":null,"username":"XXXXXXX","submitted_at":"2019-12-10 18:52:16 +00:00","received_at":"2019-12-10 18:52:14 +00:00","submission_id":"42776798","device_submission_identifier":"5e071197-XXXXXXXXXXXXXXX","submission_counter":"1","form_name":"2.

    {"initial_questions":{"values":[{"conducted_on":{"value":"2019-12-10"},"start_time":{"value":"2019-12-10 14:45:32"},"shift":{"value":"afters"},"operator_name_":{"value":"XXXXXXXXXXXX"},"Machine":{"value":"XXXXXXXXXXXXXX"}}]},

    "Work_Information":{"values":[{"Part_number":{"value":"XXXXXXXXXX"},"_1st_or_2nd_end_Machining":{"value":"Both"},"Work_Area_Tidy_":{"value":"Yes"},"Yes_No_Question":{"value":true}}]},

    "end_of_shift_report":{"values":[{"Number_of_good__compliment__parts_produced_":{"value":80},"Number_Of_parts_scrapped_":{"value":0},"Number_of_parts_reworked__":{"value":0},"Tooling_Last_off_ok_":{"value":"pass"},"End_Time_":{"value":"2019-12-10 21:15:07"},"Tooling_ok_after_last_off_":{"value":true},"Working_area_tidy_":{"value":true},"Any_comments_not_captured_above_":{"value":"XXXXXXXXXXXXXXXXXXXXXXX"},"End_Time":{"value":"2019-12-10 21:15:37"}}]}
    }
}

這是過程的屏幕顯示，謝謝。

將列表轉換為表格並繼續將列擴展為新的值或行，然后查看它是否形成您想要的形狀。 需要時取消旋轉列。 如果它沒有幫助，您可能需要將其中一些記錄分離到新查詢中，並構建多個表。
