For example, managers might be interested to learn that sales increased by 10% last month. But they would be fascinated to learn that Pat Smith's sales of Widgets in the Northwest region doubled last month, while the sales of all other people fell sharply. Array formulas provide a way by which Excel users can discover such useful information. Introducing the Data To explain the power of array formulas I'll use this database. I named each column of data with the label shown in row 1. By assigning names in this way we anchor the names in the gray border rows, rows 2 and 15. Introducing Array Formulas, Example 1 Let's begin our examination of this data by summarizing the sales for Jill and Joe. Here's the formula for the cell shown: J3: {=SUM(IF(Seller=$I3,Total,0))} Notice the braces that surround this formula.
The formula says that wherever TRUE appears, return the corresponding value from the Total column. Example 2. Excel VBA Tutorial - Easy Excel Macros.
