A slicer is a control that lets a user filter a Pivot Table or an Excel Table using buttons. A slicer provides the same function as using filter controls to filter a list. However, instead of drop-down menus, slicers provide large, friendly buttons that are always visible. The buttons are created automatically based on values in the data.
In the example shown, the slicer is set up to filter on the Department field in the data. Because there are five values in the data (Engineering, Fulfillment, Marketing, Sales, and Support) the slicer makes provides buttons with these names.
The term “spill” refers to a behavior where formulas that return multiple results “spill” these results into multiple cells automatically. This is part of " Dynamic Array " functionality. In the example shown, the formula in D5 is:
=SORT(B5:B14)
The SORT function returns 10 sorted results. Even though the formula is entered just once in cell D5, all 10 values “spill” into the range D5:D14 automatically.
The range of results returned by a formula that spills is called a spill range . When something on the worksheet blocks a spilled array formulas, it will return a #SPILL! error.
Spilling is a new feature available only in Excel 2021 and later .
