Dynamic Lookups with XLOOKUP and Arrays

Dynamic arrays in Excel have significantly enhanced how you can perform lookups and retrieve multiple results with a single formula. The XLOOKUP function, when combined with spilled arrays, allows you to search for several values at once and return corresponding results in a clean, dynamically updating column. This approach is especially useful when you want to look up and return data for a list of Employee IDs or any other identifiers, without writing separate formulas for each lookup.

Using array-driven lookups like this offers several advantages over traditional, individual lookup formulas. With a single formula, you can retrieve results for an entire list, and any changes to the source array—such as adding or removing Employee IDs—will automatically update the output. This reduces manual work, minimizes errors, and makes your spreadsheets more dynamic and easier to maintain.
