I understand for numbers you can use the n() function because if you do +n("comment") to a number it doesn't change the number.

What about string text? I can't use +n() and add a number to a string.

assuming you refer to:

  • =IF(A1="hello"; 10; 20)+N("add comment") works
  • =IF(A1="hello"; "x"; "y")+N("add comment") not working

for appending a hidden comment to text values you can do:

  • =IFERROR(IF(A1="hello"; "x"; "y");"add comment")

use it with wisdom
