The benefit of using array formulas in Excel is that they allow for complex calculations involving multiple criteria. Array formulas can perform calculations with multiple values at once, making it easier to analyze and manipulate data. They also provide direct access to external data sources, allowing users to retrieve and analyze data from other programs or databases directly within Excel. Additionally, array formulas automatically adjust to changes in data ranges, ensuring that calculations remain accurate as data is added, removed, or rearranged. Finally, array formulas enable the use of advanced conditional formatting, allowing users to apply formatting based on specific conditions or criteria.
