peterhui50 not sure why, try this:

let X = {"NAME","TRANSACTION_NUM"..."Column_45"}, Source = Csv.Document(File.Contents("XYZ.csv"),[Delimiter=",", Columns=150, Encoding=65001, QuoteStyle=QuoteStyle.None]), #"Promoted Headers" = Table.PromoteHeaders(Source, [PromoteAllScalars=true]), #"Removed Other Columns" = Table.SelectColumns(#"Promoted Headers",X) in #"Removed Other Columns"

peterhui50 Since x is already a list, you don't need to wrap it in curly brackets:

(X ) => {"NAME","TRANSACTION_NUM"..."Column_45"}
let
    Source = Csv.Document(File.Contents("XYZ.csv"),[Delimiter=",", Columns=150, Encoding=65001, QuoteStyle=QuoteStyle.None]),
    #"Promoted Headers" = Table.PromoteHeaders(Source, [PromoteAllScalars=true]),
    #"Removed Other Columns" = Table.SelectColumns(#"Promoted Headers",X)
in
    #"Removed Other Columns"
