Excel provides a number of different tools however we are going to focus on a couple of extremely useful ones: Auto filter, Arrays as well as a couple of extremely useful functions that include TEXT(),WEEKDAY(), IFERROR(), IFNA(), MATCH() and MOD().

Another tool used in fraud audits that do not necessarily require Excel, but can be used in conjunction with Excel, is Benford’s Law. Benford’s law is based on an observation that in certain large data sets, certain digits appear more frequently than others.
