By wrapping substrings in the asterisks, Excel evaluates the formula like this: COUNTIF counts the values where ever they appear in the cell. Since we are giving COUNTIF multiple values to look for, we receive a count for each value in an array like this: {1;0;1;1} . Finally, SUMPRODUCT returns the sum of all items in the array. Any result greater than zero returns TRUE.
