The information in this article applies to:
In Microsoft Visual Basic for Applications, you can create a custom function that will turn a nonadjacent selection of cells into an array. This is beneficial with many of the built-in Microsoft Excel functions that require a single range or an array as input and the data on the worksheet is not contained in a contiguous range.

1. Enter the following information in a worksheet:
A1: 1 B1: 2 C1: <empty> D1: 5
A2: 3 B2: 4 C2: <empty> D2: 6
=MakeArray(A1:B2,D1:D2)
NOTE: The above formula must be entered as an array formula. To enter a
formula as an array formula in Microsoft Excel for Windows, press
CTRL+SHIFT+ENTER. In Microsoft Excel for the Macintosh, press
COMMAND+ENTER.
