Combining UNIQUE with COUNTA allows you to count the number of unique entries in a dataset. Dynamic array formulas in Excel 365 enhance the flexibility and efficiency of the UNIQUE function.

Excel formulas like UNIQUE, COUNTIF, and CONCATENATE offer flexibility for identifying and handling duplicates in complex datasets.

If you need to average a list of values in Microsoft Excel that contain duplicates without including the duplicates, don't fret over a complex expression when you can easily remove those duplicates.

How easy was that? Without that unique list, the solution is much more complex. Excel’s COUNTA () function counts the number of cells in the referenced range that aren’t empty.
