(question from the web (https://www.mrexcel.com/board/threads/m-code-to-strip-almost-all-non-alphanumeric-characters-from-a-column.1163213/#post-5647563))

In PQ in a column named Thru, I'd like to delete all non-alphanumeric characters with the exception of + and -. Anyone know M code step(s) to accomplish this following a step called #"Promoted Headers"?


Text = Table.TransformColumnTypes(#"Promoted Headers",{{"Thru", type text}}),
TS = Table.AddColumn(Text, "Custom", each Text.Select([Thru],{"A".."Z","a".."z","0".."9","+","-"})),
RC = Table.RemoveColumns(TS,{"Thru"}),
Rename = Table.RenameColumns(RC,{{"Custom", "Thru"}})
