Count Without Duplicates in Excel

Count Unique Values with Functions

To count unique values among duplicates in Excel, utilize the combination of functions such as IF, SUM, FREQUENCY, MATCH, and LEN. The FREQUENCY function counts the number of unique values effectively. It must be entered as an array formula because it returns an array of numbers. Press Ctrl+Shift+Enter after typing the FREQUENCY formula to execute it as an array formula.

Using Advanced Filter

The Advanced Filter feature can count unique values among duplicates by extracting them to a new location. After copying the unique values, use the ROWS function to count the number of items in the new range, providing a count of unique values.

Utilizing Excel Formulas

Excel formulas like =COUNTIF, =COUNTA, and =UNIQUE can be employed to identify and count unique items. The =COUNTIF function helps in counting instances of specified criteria in a range, while =COUNTA counts non-blank cells. The =UNIQUE function, available in newer versions of Excel, extracts unique values directly.

Array Formulas for Distinct Counts

Array formulas using MATCH and IF functions can be used to count distinct values. MATCH returns the relative position of an item, and IF evaluates whether the condition is true or false. Combine these with SUM to count distinct values. Remember, the IF function requires logical_test, value_if_true, and value_if_false arguments.
