Excel Fun with New Functions

February 25, 2020

Dynamic arrays, Excel's new functions, and more, in this week's Excel news. Visit my Excel website for more tips, tutorials and videos, and check the index for past issues of this newsletter.

### New Excel Functions

The new Excel functions and dynamic arrays are finally available for everyone who's using Excel for Office 365, with monthly updates. Try them out -- they're great!

I used dynamic arrays to make dependent drop downs, and it was really easy. This animated screen shot shows how they work, with lists that change almost magically.

• In cell F2, select a region (based on dynamic array that starts in D7)
• In cell F7, dynamic array shows employees for the selected region
• In cell G2, the drop down shows that list of employees

#### How It Works

In D7, the new SORT and UNIQUE functions create a dynamic array of region names

=SORT(UNIQUE(A2:A11))

In F7, the new SORT and FILTER functions create a dynamic array of employees for the selected region

=SORT(FILTER(A2:B11, A2:A11=F2),2)

Data Validation creates the drop downs. Refer to the dynamic array starting cell, followed by the new Spill Operator, #: =\$D\$7#

### Quick Tip - Empty Cells

Have you ever written a formula to get a value from one cell, unless there's something in another cell?

For example, this formula returns the value from B2, unless there's something entered in cell A2:
=IF(A2="", B2, A2)

But what happens if both cells are empty? The result is a zero, like the one in cell C4.

If you want a cell that looks empty instead, use the T function:
=IF(A2="", T(B2), A2)

NOTE: My weekly planner Excel template also uses T, to avoid zeros in the planner cells.

### Pancake Day

Happy Pancake Day! Shrove Tuesday is always 47 days before Easter, and there's an Easter date calculation page on my Contextures site, if you want to plan for next year. We enjoy our pancakes with Canadian maple syrup, so let's hope there isn't another maple syrup heist!
