Determining a Value of a Cell

You already know that a cell in a worksheet can contain any number of different items: numbers, dates, formulas, and so on. There may be times when you want to determine the underlying value in a cell, without regard to the way the cell is formatted. For this need, Excel provides the N worksheet function. For instance, let's assume that cell F17 contains a date. If you use = N(F17) as your formula, the value returned by the formula is the underlying serial number used for the date.

Besides returning date serial numbers, the N worksheet function returns a number if the referenced value or cell can be resolved to a number, a 1 if the value or cell can be resolved to the logical value True, and a 0 for anything else. The following provides a few examples of how the N worksheet function works:

Value in F17 Returned by = N(F17)
3/11/99 36230
37.14 37.14
TRUE 1
Quarter 1 0
5:40 0.236111

Hi Allen

Greetings from New Zealand, I trust you are well.

There's a couple of other uses for the N function, which I discovered by accident:

1. It can be added at the end of any formula to store a useful comment.
eg =SUM(A1:A365)+N("all 2016 sales")

Because N("any text string") has a value of 0, it doesn't alter the SUM, but allows the comment to remain with the formula. I find this easier than the more intrusive Comment feature, and is an alternative to Named Ranges/Formulae.

2. As a security feature, of sorts.
eg =NetProfit/N(A1), where NetProfit is a named range, and cell A1 contains nothing, or some innocuous text, but allows the above formula to display the value of NetProfit when the value 1 is entered, almost like a password.

Before this, the formula will yield #DIV/0! and will appear to be an error, whereas it is a deliberate result until 'the password' is entered.

One variation of this is using a multiplier or divisor in the cell that N refers to, to deliberately disguise or alter results.

This is made even more obtuse by changing the text colour of the 'password cell' to white, so the password - the argument of N - can be hidden in plain view.

These approaches will baffle many people because many people are unaware of the existence of N. Of course, someone whose middle name is Sherlock will trace this quite quickly, but it's not for them ;)

3/11/99, 37.14, TRUE and 5:40 could all be strings that only appear to be numbers, in which case the N function would return 0. Similarly, Quarter 1 could be a number formatted to appear as a string.

When using date examples, you should use a date that is not ambiguous.

In this tip, you give an example date of 3/11/99

Anyone in America reading this date will see it as 11th March

Anyone in England reading the date will read it as 3rd November

I appreciate that in this example it doesn't really matter, but if you used a date that was higher than 12th of the month (eg 15th), it would simplify the example by removing ambiguity
