Replace character only at the end of string using Power Query (Regex $)

[CrisYan]

Hi! I need some help please :).

I want to replace two characters ONLY if are placed at the end of string of one column.

I'm using Power Query and the following Query to replace the " L" characters (notice the leading space).

= Table.ReplaceValue(#"Ant_Query"," L","",Replacer.ReplaceText,{"COLUMN_TO_APPLY"})

But the results are not what I need.

Desirable:

"TEST L" --> "TEST"
"TEST LONG" --> "TEST LONG"

"TEST LONG L" --> "TEST LONG"

Actual:

"TEST L" --> "TEST"
"TEST LONG" --> "TESTONG"
"TEST LONG L" --> "TESTONG"

Using the "( L)$" Regex to search and replace the value would do the trick.

TY very much for the help, and Regards!

You can use the following formula:

= Table.TransformColumns(
    Ant_Query,
    {{"COLUMN_TO_APPLY", 
      each if Text.EndsWith(_," L") 
           then Text.Start(_,Text.Length(_)-2) 
           else _,
      type text}})
