I have 3 columns in excel. I want to find unique values in the columns A, B and C.

So:

- by looking in column A, I want to find the unique values that are not in B or C.
- by looking in column B, I want to find unique values that are not in column A or C.
- by looking in Column C, I want to find unique values that are not in column A or B.

This is what I put in column A

```
=IF(OR(MATCH(A3,$B$3:$B$631,0),(MATCH(A3,$C$3:$C$408,0))),"Match",A3)
```

This is what I put in column B

```
=IF(OR(MATCH(B3,$A$3:$A$857,0),(MATCH(B3,$C$3:$C$408,0))),"Match",B3)
```

This is what I put in column C

```
=(IF(OR(MATCH(C3,$A$3:$A$857,0),(MATCH(C3,$B$3:$B$631,0))),"Match",C3)
```

This gives me duplicate values in the three columns I need them to be unique. Maybe I'm just making this very complicated. Any idea on how to do this?

The table example:

```
A B C
1 2 2
2 3 3
3 7 7
4 8 11
5 9 12
6 10 13
```

In this instance, for I want the unique # in each column. So, for column A the unique values that are not in columns B or C are = to 1,4,5,6. In column B the unique values, that are not in A or C, are =8,9, 10. In column C the unique values, that are not in B or C are = 11, 12, 13. I want to make a formula in columns D, E, F for these three formulas.

A B C

1 2 2

2 3 3

3 7 7

4 8 11

5 9 12

6 10 13

In this instance, for I want the unique # in each column. So, for column A the unquie values that are not in columns B or C are = to 1,4,5,6. In column B the unique values, that are not in A or C, are =8,9, 10. In column C the unique values, that are not in B or C are = 11, 12, 13. I want to make a formula in columnc D, E, F for these three formulas.

## Best Answer

You can use an array formula

^{†}like the following in D1:The formulae in the other columns are similar:

E1:

F1:

And from your example table, I get these:

If your formula starts on a different row than the first, the formula will need to be changed a bit because it uses

`ROW()`

which is dependent on the row the formula is placed in.^{†}Note: To use the formula, you have to press and holdCtrl+Shiftthen pressEnterafter inserting it.
