Pivot Column, Multiple Row to Column.

Hello vazmor 

check out this solution. This code fetches the rawdata of every second column with offset 1 and uses every second column the first entry as column name.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclTSUTIEYicgNgFiZyA2V4rVgcgYQWVMoTIWcBljqIwZVMZSKTYWAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t, Column3 = _t, Column4 = _t, Column5 = _t, Column6 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}, {"Column2", Int64.Type}, {"Column3", type text}, {"Column4", Int64.Type}, {"Column5", type text}, {"Column6", Int64.Type}}),
    CreateData = List.Transform
    (
        List.Alternate(Table.ColumnNames(#"Changed Type"), 1,1),
        (columnname)=> Table.Column(#"Changed Type", columnname)
    ),
    CreateColumnnames = List.Transform
    (
        List.Alternate(Table.ColumnNames(#"Changed Type"), 1,1,1),
        (header)=> Table.Column(#"Changed Type", header){0}
    ),
    CreateFinalTable = Table.FromColumns
    (
        CreateData,
        CreateColumnnames
    )
in
    CreateFinalTable
