One of the most commonly used Microsoft programs, Excel is highly useful for data collecting, processing, and analysis. To fully harness Excel’s powers, though, you need to make use of formulas.
Excel formulas allow you to perform calculations, analyze data, and return results quickly and accurately. The usefulness of formulas is even greater once you start dealing with large data sets. With the correct formula, Excel can process vast amounts of information in a matter of seconds.
