Which of the following accurately describes the function of the 'Spill Range' feature introduced in newer versions of MS Excel?

Correct option is C

The correct answer is: (C) It dynamically resizes a formula's output range when the formula returns multiple values.

• The 'Spill Range' feature in newer versions of Microsoft Excel (Excel 365 and Excel 2019 onward) refers to the dynamic output area that a formula occupies when it returns multiple values.

• When a dynamic array formula is entered, Excel automatically "spills" the results into adjacent cells, creating what is called a spill range.

• This eliminates the need for Ctrl+Shift+Enter used in older array formulas.

• Introduced officially in Excel 365 (2018/2019), dynamic arrays are now default behavior.

• The top-left cell of a spill range contains the formula; other cells display results but cannot be edited manually.

• If another value or formula is obstructing the spill range, Excel returns a #SPILL! error.

• A spill range reference can be created using the @ operator or # symbol (e.g., =A1# refers to the entire spill range starting from A1).

• Dynamic array formulas increase efficiency and reduce the need for helper columns.

• Option A refers to collaborative editing, which is a feature of Excel Online or Office 365 but not related to spill ranges.

• Option B is related to AutoSave, which is part of OneDrive integration, unrelated to formulas or spill ranges.

• Option D refers to Data Validation, used to restrict inputs in cell ranges—not the behavior of formulas.

• Spill ranges are also used in dynamic dashboards, reports, and when working with large data transformations without VBA or Power Query.
