So I have this column with frequently occurring data. I’ve sorted the unique values and I am looking to calculate the number of occurrence of each individual data.

One way of doing this is:

- Select the range with all recurring data
- Copy the data to a new page / location
- Select the newly pasted data
- Under the Data tab, click Remove Duplicates
- Apply the below formula to your list

```
=COUNTIF(A:A,A1)
```

Alternatively, if you are filtering the data, you can simply use the same formula on your existing list since you would be filtering out the duplicates anyways.

### Answer：

Create a pivot table. That’s what they do.

### Answer：

First you can use combination of `INDEX(), MATCH()`

function to extract unique values from your list. Then use `Countif()`

function to count occurrence. To extract use below formula.

```
=IFERROR(INDEX($A$2:$A$10,MATCH(0,INDEX(COUNTIF($C$1:C1,$A$2:$A$10),0,0),0)),"")
```

To count occurrence use following formula.

```
=COUNTIF(A:A,C2)
```

Alternatively you can use

`Advance Filter`

method to extract unique values then use`COUNT()`

function.

### Answer：

Being that you already have the unique values, the answer to your question is to use the `COUNTIF`

formula.

`=COUNTIF(A:A,C2)`

then drag down

The assumptions (which are consistent with your screenshot) for the formula are:

Column A has your base data with the multiples in it

Column C has your unique values and they start on row 2

The formula is pasted into D2 and dragged down
