In an excel sheet i have number in A colum.Suppose,in column a the number are as follows:

1

2

3

7

8

11

12

## 13

I need a formula in excel to find out only those numbers which are missing in the list.For example,in the above list,4,5,6,9,10 numbers are missing.

Here’s an updated version of the missing numbers formula using Aggregate

```
=IFERROR(AGGREGATE(15,6,ROW(INDEX(A:A,MIN(A$1:A$10)):INDEX(A:A,MAX(A$1:A$10)))/(COUNTIF(A$1:A$10,ROW(INDEX(A:A,MIN(A$1:A$10)):INDEX(A:A,MAX(A$1:A$10))))=0),ROW()),"")
```

### Answer：

Try using a combination of COUNTIF and IF function.

Assuming the numbers in the list are in columns A1:A8 and the number in question is in B1, type this in a cell:

IF(COUNTIF($A$1:$A$8,$B$1) > 0, “IT EXISTS”, “IT DOESN’T EXISTS”)
