hi shahid_tanmoy ,

see this example:

 

 

create two blank queries.

copy paste the following code in the advanced editor.

 

Ouput:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8nRRqDm0QME3Ma80LTG5pLQotQjIBQl5VBakFuVk5mUD2RioRilWJ1rJEKo0JLU4JxGbMgWIgoySkgIrff0SkDK95PxDC0AQJg02yQhqkl9mcXFiHlYb4cbkgdUAzckFGQMUB5tgDDUhKDUvsTSnBJt+7O7D6W6wsSZQY8Pyc8rycfkPma9LpMGmIJZCSH5lfgnWoAOHhr4jkS6NBQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}}),
    #"Split Column by Delimiter" = Table.SplitColumn(#"Changed Type", "Column1", Splitter.SplitTextByDelimiter("|", QuoteStyle.Csv), {"Column1.1", "Column1.2", "Column1.3", "Column1.4"}),
    #"Removed Columns" = Table.RemoveColumns(#"Split Column by Delimiter",{"Column1.4"}),
    #"Promoted Headers" = Table.PromoteHeaders(#"Removed Columns", [PromoteAllScalars=true]),
    #"Changed Type1" = Table.TransformColumnTypes(#"Promoted Headers",{{"ID ", Int64.Type}, {"  Manufacturer  ", type text}, {"  Hyperlink             ", type text}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type1", "Custom", each if Text.Contains([#"  Hyperlink             "], "http://") then 1 else 0),
    #"Renamed Columns" = Table.RenameColumns(#"Added Custom",{{"  Manufacturer  ", "Manufacturer"}, {"  Hyperlink             ", "Hyperlink"}, {"ID ", "ID"}}),
    #"Appended Query" = Table.Combine({#"Renamed Columns", TabletoAppend})
in
    #"Appended Query"

 

 

Table to Append

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlPSUYKi2FgA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ID = _t, Manufacturer = _t, Hyperlink = _t, Custom = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ID", Int64.Type}, {"Manufacturer", type text}, {"Hyperlink", type text}, {"Custom", type text}})
in
    #"Changed Type"
