The primary benefit of using array formulas in Excel is that they allow for complex calculations involving multiple criteria.
Array formulas can process multiple values or ranges in a single formula, enabling users to perform calculations that are not possible with standard formulas. This allows for tasks such as summing only certain values based on specific criteria, performing calculations across multiple data ranges simultaneously, and generating multi-dimensional calculations, which can significantly enhance data analysis and output.
While other options mentioned may provide some level of enhancements or features, they do not directly capture the core advantage of array formulas as well as this one does.
