M语言简单示例--加载多个相同格式的文件到一个文件中

1.先打开文件夹中的其中一个文件
2.启动编辑器,做相应的基础转换操作

    MySheet1 = 源{[Name="MySheet"]}[Data],
    提升的标题 = Table.PromoteHeaders(MySheet1, [PromoteAllScalars=true]),
    更改的类型 = Table.TransformColumnTypes(提升的标题,{{"Region", type text}, {"Market", type text}, {"Branch_Number", Int64.Type}, {"Customer_Name", type text}, {"State", type text}, {"Effective_Date", type text}, {"Product_Description", type text}, {"Revenue", type number}, {"TransactionCount", Int64.Type}}),
    删除的列 = Table.RemoveColumns(更改的类型,{"Branch_Number"})
in
    删除的列

let GetMyFiles=(FilePath, FileName) =>
let
    源 = Excel.Workbook(File.Contents("C:\Users\DengXiaoju\Desktop\Sample Files\Chapter 12\test\WEST.XLS"), null, true),
    MySheet1 = 源{[Name="MySheet"]}[Data],
    提升的标题 = Table.PromoteHeaders(MySheet1, [PromoteAllScalars=true]),
