Chapter 18: Understanding and Using Array Formulas

Using Multicell Array Formulas
This section contains examples that demonstrate additional features of multicell array
formulas (array formulas that are entered into a range of cells). These features include cre-
ating arrays from values, performing operations, using functions, transposing arrays, and
generating consecutive integers.
Creating an array from values in a range
The following array formula creates an array from a range of cells. Figure 18.8 shows a
workbook with some data entered into A1:C4. The range D8:F11 contains a single array
formula:
{=A1:C4}
FIGURE 18.8
Creating an array from a range
The array in D8:F11 is linked to the range A1:C4. Change any value in A1:C4, and the corre-
sponding cell in D8:F11 reflects that change. It’s a one-way link, of course. You can’t change
a value in D8:F11.
Creating an array constant from values in a range
In the preceding example, the array formula in D8:F11 essentially created a link to the
cells in A1:C4. It’s possible to sever this link and create an array constant made up of the
values in A1:C4:
- Select the cells that contain the array formula (the range D8:F11, in this
example). - Press F2 to edit the array formula.
