@xkapr Here are 2 ways to solve this, paste the whole code in the Advanced Editor in PQ.

 

let
    Source = 
    Table.FromRows (
        Json.Document (
            Binary.Decompress (

HI! @xkapr 

 

Please replace this code in the advance editor.

 

let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WSlTSUUoCYiOlWJ1opWQgKwWIjZViYwE=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Col1 = _t, Col2 = _t, Col3 = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Col1", type text}, {"Col2", type text}, {"Col3", Int64.Type}}),
#"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Changed Type", {"Col3"}, "Attribute", "Value"),
#"Reordered Columns" = Table.ReorderColumns(#"Unpivoted Columns",{"Value", "Col3", "Attribute"}),
#"Removed Columns" = Table.RemoveColumns(#"Reordered Columns",{"Attribute"})
in
#"Removed Columns"
