Array formulas are a powerful feature in Excel that can be used to perform complex calculations and manipulate large datasets. They allow you to work with arrays of values instead of single cells, enabling you to perform calculations across multiple cells at once. Array formulas can be used for tasks like finding the maximum value in a range, counting unique values, or performing mathematical operations on multiple rows or columns.

Array formulas are a bit more advanced than regular formulas in Excel. They are used when you want to perform calculations on multiple cells or ranges at once. Array formulas can be used to find the highest or lowest value in a range, calculate a sum or average, or even perform complex calculations involving multiple arrays. They are a valuable tool for advanced Excel users who need to handle complex data analysis and calculations.

Array formulas in Excel allow you to perform calculations on multiple values simultaneously. They are enclosed in curly brackets and are entered by pressing Ctrl+Shift+Enter instead of just Enter. Unlike regular formulas, array formulas can return multiple results and perform calculations across multiple rows and columns.
