[ASK] Remove CRLF at the end of text file

Hi :-)
What is the best way to remove the CRLF at the end of text file? Is there any build-in function to do it?

For example, my text file content:

Line1
Line2


When I open it with notepad and press Ctrl+End, the cursor will placed on Line3 Col 1, I wish to remove that CRLF at line 3 so when I press Ctrl+End on notepad,
the cursor will be at Col 6 at Line 2.

Thanks :-)
