The use of Excel functions is a valuable skill in the workplace. Whether you’re monitoring sales, managing inventory, budgeting, or doing any other task, knowing different Excel formulas comes in handy on the job. Some of the functions they were taught were CONCATENATE (), VLOOKUP(), and DATEDIF(). At the end of the session, they applied their learnings by taking a test.
