Adding comments within formulas using the “N” function

By

As you’re getting more advanced with Excel, you’re probably finding that you’re not quite sure what a formula does if you look back at it after a few days or weeks.

Did you know that you can add a description within your formula and not affect the result? The “N” function turns non-numbers into numbers (dates to serial numbers, for example) and anything else to zero (i.e. text). So you can add a comment by using the “N” function to replace your text with zero without affecting the formula itself. Confused? Try this and see what happens:

=7*4+N("Number of days in 4 weeks")

You should see that everything within the “N” brackets is ignored, therefore allowing you to add your own notes to formulas and better remember what they do!
