Easily count occurrences of duplicates in a column and then delete duplicate rows based on this column in Excel

This section will introduce the FREQUENCY function to quickly count all numbers if they fall within a given number range.

For example I have a list of numbers in Column A as the left screenshot shown.

1. Please list your given ranges you will count numbers within besides the list of numbers, for example Column B.

In our case we type 25, 50, 75, and 100 into Range B2:B5. That’s mean we will count numbers between 0 and 25, count numbers between 25 and 50, etc. See right screenshot:

2. In another column, says Column C, select the same number of cells as those in Column B (here I select cell C2:C5 at the same time), type the formula =FREQUENCY(A2:A24,B2:B5), and press the Ctrl + Shift + Enter keys simultaneously. And then you will get the total amount of numbers between the specified ranges. See right screenshot:

Note: In above formula, A2:A24 is the list of numbers you will count, B2:B25 is the column with the specified ranges you will count numbers within.

If you have Kutools for Excel installed, you can count numbers if they are falling within a given range without applying formulas in Excel.

1. Select the list of numbers you will count, and click Kutools > Select > Select Specific Cells. See screenshot:

2. In the opening Select Specific Cells dialog box, please (see the second screenshot above):

(1) Check the Cell option in the Selection type section;

(2) In the Specific type section, select the Greater than or equal to from the first drop down list, and type a minimum value of the given range into following box; select the Less than or equal to from the second drop down list and type the maximum value of the given range into the following box, and then check the And option. See below screenshot:

(3) Click the Ok button.

3. All numbers falling within the given range are selected. And at the same time a dialog box pops up and shows how many cells have been selected. See screenshot.

Click the OK button to close dialog boxes.

Sometimes, you may want to count any values in one column if they fall in another column, you can apply Kutools for Excel’s Select Same & Different Cells utility to easily get it done in Excel.

1. Click Kutools > Select > Select Same & Different Cells to open the Compare Ranges dialog box.

2. In the opening dialog box, please do as follows:

(1) Specify the column you will count values in into the Find values in box;

(2) Specify the criteria column you will count values by into the According to box;

Note: If two columns have the same header, please check the My data has headers option.

(3) Check the Same Values option in the Find section;

(4) Click the Ok button.

3. Now all values falling in the criteria column are selected, and a dialog box pops up and shows how many cells have been selected. See the second screenshot above:

Click the OK button to close dialog boxes.
