Data left to right

Hello netanel 

you can transform you column (you could basically also add a custom column, but that would only make more unneccessary data) and apply the function in my code

    Reverse = Table.TransformColumns
    (
        #"Changed Type",
        {
            {
                "YourColumn",
                each Text.Combine(List.Reverse(Text.ToList(_))), 
                type text
            }
        }
    )

if you need more columns to be transformed, you have to add a another nested list. In case I can show you that too. Here a complete code example to see how it works

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WckxKVkhJTbNXitWJVvLPSFSoSElUio0FAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [YourColumn = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"YourColumn", type text}}),
    Reverse = Table.TransformColumns
    (
        #"Changed Type",
        {
            {
                "YourColumn",
                each Text.Combine(List.Reverse(Text.ToList(_))), 
                type text
            }
        }
    )
in
    Reverse
