    Hi, 

     

    The important step is:

     

    #"Columns" = Table.ColumnNames(#"Changed Type")

     

    This is the M code of the example.

     

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i44FAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t, Column3 = _t, Column4 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}, {"Column2", type text}, {"Column3", type text}, {"Column4", type text}}),
    #"Columns" = Table.ColumnNames(#"Changed Type")
in
    #"Columns"

    Regards.
