Check if 1 notation is correct/valid

[Gurnoor Rana]

Hi,
Using Apps Script, I am trying to take user's input for a cell position as A1 notation and then edit a value there.
Before doing that, I want to check if what they typed is valid a1 notation text or not. I know it might likely be a regex check but I don't know about it that much.
Thanks for the help.

I would first try to see if apps script throws an error if the userinput is not a valid A1 range. Something like:

if ( !sheet.getRange(USERINPUT).getA1Notation()  ) {
  return "Please enter a valid range in the form 'A1' "

Unfortunatly sheet.getRange throws an exception before we get to evaluating getA1Notation().
It's not a big deal since I planned on just throwing an exception myself, but it does keep me from throwing the specific exception I wanted.
