Removing Last Delimiter from Each Row

The goal is to remove the last comma delimiter of each row. Some rows have one item and is finalized with a comma delimiter. Some rows have multiple items separated by comma delimiters. But all rows have a comma as the final character. 

 

Any advice on how to remove the last comma delimiter of each row is greatly appreciated. Below is sample data for context. 

 

Current Output (notice the last comma of each row)

Test_Data
Black,
Black, White, Red,
Blue, Orange,
Green, Blue, Black, Red, Orange,

 

Expected Output 

Test_Data
Black
Black, White, Red
Blue, Orange
Green, Blue, Black, Red, Orange

@win_anthony Use the Transform tab. Extract, text before delimiter. Use comma as delimiter and From the end of input and 0.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcspJTM7WUYrVgTEVwjMyS1J1FIJSU2DCpUCuf1FiXnoqRMS9KDU1T0cBIgHVBVKOUBQLAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Test_Data = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Test_Data", type text}}),
    #"Extracted Text Before Delimiter" = Table.TransformColumns(#"Changed Type", {{"Test_Data", each Text.BeforeDelimiter(_, ",", {0, RelativePosition.FromEnd}), type text}})
in
    #"Extracted Text Before Delimiter"

@win_anthony No worries! You shouldn't feel stupid, we all forget stuff we have learned at some point! Happens to me all the time!
