How to find values that repeat x times

Svetik 

PivotTable could work as

and you may filter it on value >=10

Svetik 

=TEXTJOIN(", ",,DROP(REDUCE("",SEQUENCE(ROWS(UNIQUE(A1:A15))),

LAMBDA(x,y,VSTACK(x,IF(COUNTIF(A1:A15,INDEX(UNIQUE(A1:A15),y))=C1,

INDEX(UNIQUE(A1:A15),y),"")))),1))

With Office 365 or Excel for the web you can apply this formula.

Hi Svetik,

You can try to use COUNTIF function to achieve your goal:

COUNTIF function - Microsoft Support

1. Organize Your Data

Organize all your client data for example in a single column. Let's say your list starts from cell A1.

2: Count the Occurrences

In any empty cell, use the `COUNTIF` function to count how many times a specific value repeats in your data. For instance, if you want to find clients who made 10 purchases:

=COUNTIF(A:A, "10")

* you can replace "10" with the value you want and then press Enter to get the result (count).

This formula tells Excel to count how many times "10" appears in column A.

3: Filter the Results

To filter clients who made (for example) exactly 10 purchases, follow these steps:

1. Click on the header of the column containing your client data (e.g., column A).

2. Go to the "Data" tab in Excel.

3. Click on the Filter icon on the column header you selected.

4. A dropdown menu will appear in the column header. 

5. From the submenu, select "Equals" or "Custom Filter," depending on your preference.

6. In the dialog box that pops up, enter the count you obtained from the `COUNTIF` function (e.g., 10).

7. Click "OK" or "Filter."

Excel will now display only the rows where clients made exactly 10 purchases. You can repeat these steps for different purchase counts, such as 5 and 7, by adjusting the value in the `COUNTIF` formula and applying the filter accordingly.
