Since LT doesn't handle lisp you are limited to using a script. However a script may work just fine. If the point you want to create is a standard point entity and not a symbol with attributes, the following approach will work. A symbol with attributes could be accomplished similarily.
First delete the column with comment/point number. Save the excel file to csv format. You'll then have a text file with N & E separated by commas. At the top oif the file, type in AutoCAD commands to start the point function:
Multiple
point
E1,N1
E2,N
etc. etc
Save the file with a .scr file extension. Execute this file by typing SCRIPT within AutoCAD. After it runs you'll need to hit Escape to stop the multiple point command.
Good luck. Let us know if questions.
