Hi gaiusgw ,

you can do it with your sample data in Power Query like this:

// Table
let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("lZTJboMwEIZfJeIMknebI1vUxQkoIYeK5hApHCpVPVRqn79jIMFQMOGAZaT5/tldVZ6u68/L5v0HISI2+vJbf13rb8/34leMhOTmBh8mcBCqvLNfedn1o24sCi6kMDcdJNEuj/Y7+GHK2PuYkcZ4Vr8E/ZB2+hTBIdEjCBsgii4gfOyECzuJJFWYGclE97HzEE/a5BM2c56HUOMa+4i7w71Dx3wFtC0wom2WQRE9H3X2Ns7WwUKBwikU+5TQQRk0+JG49QPtPh36alAlbdM0U5hgw1gTIaQ7jyHUxQAex8LMjFy6XyNcdMp2LwjmQ+WyM4qDMu3FFXVX8B83kp/jtpoQFtqTCVWU0s2U0AEu6ciZYIO9BKvbXlqZhDJ0aj/BchHK7YCYcqfeI/24PsIISNNywxmyw3+BZjHz3MSHoLD6sFCbMXZrw8IzdMfWU7R9+SysWZjzHw==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [CUSTNAME = _t, Style = _t, Color = _t, Quantity = _t, #"Current Sales" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"CUSTNAME", type text}, {"Style", type text}, {"Color", type text}, {"Quantity", Int64.Type}, {"Current Sales", type number}}),
    #"Merged Columns" = Table.CombineColumns(#"Changed Type",{"Style", "Color"},Combiner.CombineTextByDelimiter("#", QuoteStyle.None),"Merged"),

in
    #"Split Column by Delimiter"
