    Hey As9124141636 ,

     

    I think I found a solution.

    I split the table into different years. Then I'm looping over each table and do the transformation.

     

    Please check the attached file. When you open the Power BI file, you have to adapt the parameter "PathToXLSXFile" to the path and name of your XLSX file, for example to "C:\temp\Transpose.xlsx".

    Afterwards the rest should load automatically.

     

    If you need any help please let me know.
    If I answered your question I would be happy if you could mark my post as a solution ✔️ and give it a thumbs up 👍

    Best regards

    As9124141636 , Having them in one sheet is not a good idea. Check if this code can help

     

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("fZJLEgMhCETvMuss5NMCZ5nK/a8RGFNJqsK4QpQHbet5HnQ8DjIxWC7YY4yMgolKGdPrnIfQzIVD8Y3Px3lwlVEw39M+ERVZ3vkHlswMCNqMNh0eP/TMdnrRWscQ0blTTkLSDq8yUtiq7/HsbtHSNTNb80Xd0KKpvqXtkj5VNnQ+Crz3zS/faMRGucfsldeuiUI2o8EAtTSNdXHzjevp6fpO/3h1hdK62M1/CTLu6dp24uXqjXZVt+bFny8=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"2011" = _t, A = _t, B = _t, C = _t, D = _t, E = _t, F = _t, G = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"2011", Int64.Type}, {"A", Int64.Type}, {"B", Int64.Type}, {"C", Int64.Type}, {"D", Int64.Type}, {"E", Int64.Type}, {"F", Int64.Type}, {"G", Int64.Type}}),
    #"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Changed Type", {"A", "B", "C", "D", "E", "F", "G"}, "Attribute", "Value"),
    #"Renamed Columns" = Table.RenameColumns(#"Unpivoted Columns",{{"Attribute", "Year"}, {"Value", "Month"}}),
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Renamed Columns", {"Year", "Month"}, "Attribute", "Value")
in
    #"Unpivoted Other Columns"

      thanks

      i think you did it for one year. i want to do for all years and if new year added in excel, transform it automatically.

      I think the solution is create list of years and transform every year (in a loop) then finally append. but i dont know how to do in power query.

    Hi,

    Why is your data in such a poor format?  Why not clean it up to atlest have all years listed down a single column and then upload the Data to PowerBI?
