This example shows you how to create an array formula that counts unique values<\/strong>.<\/p>\n\n\n\n

1. We use the COUNTIF function. For example, to count the number of 5’s, use the following function.<\/p>\n\n\n\n

\"Countif<\/figure>\n\n\n\n

2. To count the unique values (don’t be overwhelmed), we add the SUM function, 1\/, and replace 5 with A1:A6.<\/p>\n\n\n\n

\"Array<\/figure>\n\n\n\n

3. Finish by pressing CTRL + SHIFT + ENTER.<\/p>\n\n\n\n

\"Count<\/figure>\n\n\n\n

Note: The formula bar indicates that this is an array formula by enclosing it in curly braces {}. Do not type these yourself. They will disappear when you edit the formula.<\/p>\n\n\n\n

Explanation: The range (array constant) created by the COUNTIF function is stored in Excel’s<\/strong> memory, not in a range. The array constant looks as follows:<\/p>\n\n\n\n

{3;1;1;1;3;3} – (three 7’s, one sun, one moon, one 5, three 7’s, three 7’s)<\/p>\n\n\n\n

This reduces to:
{1\/3;1\/1;1\/1;1\/1;1\/3;1\/3}<\/p>\n\n\n\n

This array constant is used as an argument for the SUM function, giving a result of 1\/3+1+1+1+1\/3+1\/3 = 4.<\/p>\n\n\n\n

4. The array formula below counts the number of values that occur exactly once.<\/p>\n\n\n\n

\"Exactly<\/figure>\n\n\n\n

5. If you have Excel 365, simply use the magic UNIQUE function to extract unique values.<\/p>\n\n\n\n

\"UNIQUE<\/figure>\n\n\n\n

Note: this dynamic array function, entered into cell C3, fills multiple cells. Wow! This behavior in Excel 365 is called spilling.<\/p>\n\n\n\n

6. Next, add the COUNTA function to count unique values in Excel 365.<\/p>\n\n\n\n

\"COUNTA<\/figure>\n\n\n\n

7. The formula below counts the number of values that occur exactly once.<\/p>\n\n\n\n

\"Count<\/figure>\n\n\n\n

Note: the UNIQUE function has 2 optional arguments. The default value of 0 (second argument) tells the UNIQUE function to extract values from a vertical array. The value 1 (third argument) tells the UNIQUE function to extract values that occur exactly once.<\/p>\n\n\n\n
