Converting rows to column

Hi gowtham1991 

Please try this code:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("ddC7DYAwDATQVZDrFCSQDwswAG2UgsIdFZ/9KShyh+TuLOvpLNcqq+73c+rgxcmmh+7Xl2GcIUdprqMAm8AoQk6EJthMjBLkTGg27mHRcyEdjcNY9LyQTkYfC3jfSDwbhT8CgydfjMq/gSFIay8=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Feature List" = _t, ML1 = _t, ML2 = _t, ML3 = _t, ML4 = _t]),
    
    // Unpivot all columns except 'Feature List' so ML values become rows
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(Source, {"Feature List"}, "Attribute", "Value"),

    // Remove rows where the 'Value' column is null or empty
    #"Filtered Rows" = Table.SelectRows(#"Unpivoted Other Columns", each [Value] <> null and [Value] <> ""),

    // Create a new column 'Value2' by extracting the release number from 'Value'
    // This ensures a consistent "Release X" naming format
    #"Added Custom" = Table.AddColumn(
        #"Filtered Rows", 
        "Value2", 
        each "Release " & Text.PadStart(Text.AfterDelimiter([Value], " "), 2, "0"), 
        type text
    ),

    // Remove the original 'Value' column, keeping only 'Value2'
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Value"}),

    // Rename 'Value2' back to 'Value' to maintain expected column names
    #"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"Value2", "Value"}}),

    // Pivot the table so that 'Value' becomes column headers, and ML attributes are placed under them
    #"Pivoted Column" = Table.Pivot(
        #"Renamed Columns", 
        List.Distinct(List.Sort(#"Renamed Columns"[Value])), 
        "Value", 
        "Attribute"
    ),

    // Dynamically rename the pivoted columns to maintain proper "Release X" formatting
    Custom1 = 
        let 
            tbl = #"Pivoted Column",
            ColumnNames = List.Skip(Table.ColumnNames(tbl), 1), // Skip the first column ('Feature List')
            RenameTo = List.Transform(
                ColumnNames, 
                each "Release " & (try Text.From(Number.From(Text.AfterDelimiter(_, " "))) otherwise null)
            )
        in 
        Table.RenameColumns(tbl, List.Zip({ColumnNames, RenameTo}))
in
    Custom1
