Excel’s MAP function is genius

If you've ever found yourself copying the same formula down hundreds of rows in Excel, you know how tedious it gets. The usual approach, dragging formulas, adjusting cell references, and hoping nothing breaks, works, but it's far from efficient. Excel's MAP function changes that. Instead of applying formulas one cell at a time, MAP processes entire ranges of data at once, to make your Excel spreadsheets cleaner and your workflow faster.
