jsherman-q - I would just create a new column that does the necessary operation, remove the original column and then rename the new column to the old colum, like this:
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W0itIyqxQ0lHKz0uFMGN1gIJJiSVAsZLyfDALLFSRUwxSV5JRlJoK4cTGAgA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}, {"Column2", type text}}),
#"Inserted Text Before Delimiter" = Table.AddColumn(#"Changed Type", "Text Before Delimiter", each Text.BeforeDelimiter([Column2], "."), type text),
#"Removed Columns" = Table.RemoveColumns(#"Inserted Text Before Delimiter",{"Column2"}),
#"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"Text Before Delimiter", "Column2"}})
in
#"Renamed Columns"
If i'm reading that right it looks like it just remvoed the text before the delimiter ".". If so, that's not really what i want. I want ot to remove the value in column1 from column2. I used the exmaple of a file extension but in some cases my data is not a file extension and does not have the ".".

That worked thank you. I would have psoted data but it I is private data so I would have had to come up with sample data, which I was hoping I wouldn't have had to.
