# Excel: How to Use a Concatenate If Formula

The following examples show how to use a concatenate if formula in Excel.

### Example 1: Concatenate If (By Column)

Suppose we have the following data in Excel:

We can use the following formula to concatenate cells in column A and B only if the value in column B is equal to “Good”:

```=CONCAT(IF(B2="Good", A2:B2, ""))
```

The following screenshot shows how to use this formula in practice:

If the cell in column B is equal to “Good” then the value in column C is equal to the concatenation of the cells in column A and B.

Otherwise, this formula simply returns a blank value.

### Example 2: Concatenate If (By Row)

Once again suppose we have the following data in Excel:

We can use the following formula to concatenate all of the cells in column A where the value in column B is equal to “Good”:

```=CONCAT(IF(B2:B7="Good", A2:A7, ""))
```

The following screenshot shows how to use this formula in practice:

Notice that the value in cell C2 is the result of concatenating every value in column A where the corresponding value in column B is equal to “Good.”
