Learn how the pound sign (#) in Excel formulas references dynamic array spill ranges for efficient data manipulation.

540 views

In Excel formulas, the pound sign (#) is used in dynamic array formulas to refer to the entire spill range of an array. For example, if you have a formula that spills over multiple cells, using `#` after the cell reference (e.g., `A1#`) tells Excel you're referencing the entire array that starts in A1. This is particularly useful for summarizing or manipulating the results of dynamic arrays without needing to specify individual cell references.
