As Wyn has already said, Excel would not be the right tool for that. In fact, I can't think of any normal office software product, off the shelf, that could do that.
HOWEVER, if all of your entries contain similar kinds of entries (and if this is something you're going to be doing for the future)...I CAN conceive of using Excel if you were to re-think this as a database rather than simply a place to store casual notes.
IF, for example, you always record DATEFIRSTMET, BIRTHDAY (or some basic reference that would allow you to calculate age today or at other points in time), GRADDATE, etc., and, importantly, have standardized answers (a range of them could be created) for entries in such fields as PRETEEN PERS(onality), TEEN PERS(onality)...into which such descriptons as "rounder","shy","bookish" or whatever....
Do you get the idea? This sounds like you're a counselor in some setting....
I realize that all I'm doing is scratching the surface of how such a database could be created, and you'd always have to have a column or two to allow you to enter "non-standard" observations, or a note to self on "this is what we need to talk about next time we meet"....
What you have done so far, though, is to use Excel simply as a note taking device which happens to be in/on a computer; you've not used EXCEL for the purposes it actually serves. To do the latter, you need to re-think the way you keep those records.
