Folder Query

Hi crjackson ,

If you want to keep only the latest month's data. Please try this:

= Table.FromColumns({List.First(Table.ToColumns(PreviousStepName))} & {List.Last(Table.ToColumns(PreviousStepName))})

all steps:

let
    Source = Excel.Workbook(File.Contents("C:\Users\v-cgao\Desktop\New Microsoft Excel Worksheet.xlsx"), null, true),
    Table1_Table = Source{[Item="Table1",Kind="Table"]}[Data],
    #"Changed Type" = Table.TransformColumnTypes(Table1_Table,{{"Column1", type text}, {"Sep'22", Int64.Type}, {"Oct'22", Int64.Type}}),
    #"Demoted Headers" = Table.DemoteHeaders(#"Changed Type"),
    Custom1 = Table.FromColumns({List.First(Table.ToColumns(#"Demoted Headers"))} & {List.Last(Table.ToColumns(#"Demoted Headers"))}),
    #"Promoted Headers" = Table.PromoteHeaders(Custom1, [PromoteAllScalars=true]),
    #"Changed Type1" = Table.TransformColumnTypes(#"Promoted Headers",{{"Column1", type text}, {"Nov'22", Int64.Type}})
in
    #"Changed Type1"
