Converting List to Meaningful Data

Hi PiyushBQ 

Copy and paste my query in advanced editor

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMtX1SsxT0lGyBGITYyBhaGysFKsTrWQGlTACSViAJAwtwBIuiSWpQK4TELsAsSNY0Byq2tAcRBiYGgApc7CMBUzGBEQYmYIUmCjFxgIA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t, A = _t, B = _t, C = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type text}, {"A", type text}, {"B", type text}, {"C", type text}}),
    #"Demoted Headers" = Table.DemoteHeaders(#"Changed Type"),
    #"Changed Type1" = Table.TransformColumnTypes(#"Demoted Headers",{{"Column1", type text}, {"Column2", type text}, {"Column3", type text}, {"Column4", type text}}),
    #"Added Index" = Table.AddIndexColumn(#"Changed Type1", "Index", 1, 1),
    #"Added Conditional Column" = Table.AddColumn(#"Added Index", "Custom", each if [Column1] = "Date" then [Index] else null),
    #"Filled Down" = Table.FillDown(#"Added Conditional Column",{"Custom"}),
    #"Removed Columns" = Table.RemoveColumns(#"Filled Down",{"Index"}),
    #"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Removed Columns", {"Column1", "Custom"}, "Attribute", "Value"),
    #"Sorted Rows" = Table.Sort(#"Unpivoted Columns",{{"Custom", Order.Ascending}, {"Attribute", Order.Ascending}, {"Value", Order.Descending}}),
    #"Duplicated Column" = Table.DuplicateColumn(#"Sorted Rows", "Value", "Value - Copy"),
    #"Changed Type2" = Table.TransformColumnTypes(#"Duplicated Column",{{"Value - Copy", type number}}),
    #"Replaced Errors" = Table.ReplaceErrorValues(#"Changed Type2", {{"Value - Copy", 9999}}),
    #"Added Conditional Column1" = Table.AddColumn(#"Replaced Errors", "Custom.1", each if [#"Value - Copy"] = 9999 then [Value] else null),
    #"Filled Down1" = Table.FillDown(#"Added Conditional Column1",{"Custom.1"}),
    #"Filtered Rows" = Table.SelectRows(#"Filled Down1", each [#"Value - Copy"] <> 9999),
    #"Removed Columns1" = Table.RemoveColumns(#"Filtered Rows",{"Custom", "Attribute", "Value - Copy"}),
    #"Reordered Columns" = Table.ReorderColumns(#"Removed Columns1",{"Column1", "Custom.1", "Value"}),
    #"Sorted Rows1" = Table.Sort(#"Reordered Columns",{{"Column1", Order.Ascending}, {"Custom.1", Order.Ascending}})
in
    #"Sorted Rows1"
