Hi slyfox ,

1. In your data, if the values of the [User Name] column with similar user name are empty, then you can just delete the rows with empty values of column [User Name].

2. Or you can add a custom column and remove the rows that satisfy the condition: [User Name.1] = [Standard Name].

= Text.Select([User Name.1], {"a".."z","A".."Z"})

And the complete code is as follows:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WsjA2tzRS0lEKTsxNzCtJVAjOzSzJUAAJ+AIZSrE60UqWRhZmxkARmGC8IVgYKGpiiCxsBBY2BBuWpxCVkZiXDmFDlEOVJuaB9McCAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Id = _t, #"User Name" = _t, #"User Name.1" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Id", Int64.Type}, {"User Name", type text}, {"User Name.1", type text}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Standard Name", each Text.Select([User Name.1], {"a".."z","A".."Z"})),
    #"Filtered Rows" = Table.SelectRows(#"Added Custom", each ([User Name.1] = [Standard Name]))
in
    #"Filtered Rows"

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.
