Excel's MAP Function: Functional Mapping of Array Elements
2025-04-04
Excel's MAP function offers a powerful way to process arrays. It transforms each element in an array using a custom LAMBDA function and returns a new array. You can input multiple arrays, and the LAMBDA function will calculate the elements at corresponding positions. This makes batch data processing concise and efficient; simply define the calculation formula, and the MAP function automatically completes the mapping of all elements.
