轉換json與電力查詢（在單個列中混合列表和記錄）

Question

我想要轉換（我是一個電源查詢轉換新手）json數據。我們的目標是合併和轉換一些json文件來創建報告。 json文件由我們的Web應用程序公開的不同Feed提供。作爲學習的一部分，我們嘗試轉換單個json文件。

但場在我們的JSON數據的一個是爲通過功率查詢作爲記錄和列表類型的混合承認（在功率查詢該列中的一個顯示列表和記錄的混合）。

在這種情況下，我無法獲取這些訂單項的值。

任何解決這個問題的指針將是非常有益的

在此先感謝

請找到樣本JSON：

注一此文件中的對象應該代表在excel中排成一排。

我想在這裏分享一個外部鏈接（不確定我是否違反任何政策，如果是這樣，請糾正我），以便其他人也可以使用這些知識。 我的核心問題在www.mrexcel.com/forum/power-bi的幫助下得到了解決。通過這段代碼，我可以創建一個基於excel的工具，通過組合不同的提要爲業務準備數據集。請找爲此所需的代碼（M，而是非常具體的我輸入文件）

let 
    source = Json.Document(File.Contents("d:\path\filename.json")), 
    tabled = Table.FromRecords({source}), 
    expandListField = Table.ExpandListColumn(tabled, "thingstodo"), 
    expandRecField = Table.ExpandRecordColumn(expandListField, "thingstodo", {"propCode", "hours"}, {"propCode", "hours"}), 
    expandList2 = Table.ExpandListColumn(expandRecField, "hours"), 
    fieldForRec = Table.AddColumn(expandList2,"Rec",each if Value.Is([hours], type record) then [hours] else null,type record), 
    fieldForList = Table.AddColumn(fieldForRec, "List",each if Value.Is([hours], type list) then [hours] else null,type list), 
    removed = Table.RemoveColumns(fieldForList, {"hours"}), 
    expandRecField2 = Table.ExpandRecordColumn(removed, "Rec", {"day", "time"}, {"day", "time"}), 
    expandList3 = Table.ExpandListColumn(expandRecField2, "List") 
in 
    expandList3
