In this example, the goal is to calculate and display profit margin as a percentage for each of the items shown in the table. In other words, given a price of $5.00 and a cost of $4.00, we want to return a profit margin of 20%. Each item in the table has different price and cost, so the profit...Read more

The general goal is to return the first text value in a range. Specifically, we have dates in column B and some city names in column C. We want a formula to find the first city listed in the range C5:C16. Because some cells in C5:C16 are empty, and some contain zeros, we need to ignore...Read more
In this example, the goal is to test if a given range contains duplicate values and return TRUE if duplicates exist and FALSE if not. This is essentially a counting problem and the solution is based on the COUNTIF function, which counts values in a range...Read more
In this example, the goal is to count codes in a case-sensitive way. The COUNTIF function and the COUNTIFS function are both good options for counting text values, but neither is case-sensitive, so they can't be...Read more
This formula is more complicated than a similar formula that uses FREQUENCY to count unique numeric values because FREQUENCY doesn't normally work with non-numeric values. As a result, a large part of the formula simply transforms...Read more
Note: Prior to Excel 365, Excel did not have a dedicated function to count unique values. This formula shows one way to count unique values, as long as they are numeric. If you have text values, or a mix of text and numbers, you'll need to use a...Read more
The MATCH function returns the position or "index" of the first match based on a lookup value in a range.
MATCH supports wildcard matching with an asterisk "*" (one or more characters) or a question mark "?" (one character), but only when the third...Read more
Each item in rng is compared to each item in values and the result is an array of TRUE or FALSE values.
The double negative will force the TRUE and FALSE values to 1 and 0 respectively. Since SUMPRODUCT...Read more
