## What Does Substitute Function Do In Excel?

The SUBSTITUTE function in Excel is useful to replace or substitute a given text with another text in a given cell. This function is widely used when we send massive emails or messages in bulk. Instead of creating separate text for every user, we use a SUBSTITUTE function to replace the information.

For example, consider the below example with cell A1 showing a saying. We can see that the saying is typed incorrectly. Instead of ‘Honesty is the best policy’, it is wrongly typed as ‘Honesty is a best policy’.

Now, let us learn how to use the SUBSTITUTE function.

**Step 1:**First, select a cell to display the result. In our example, we have selected cell B1.

**Step 2:**Next, insert the SUBSTITUTE formula in cell B1.

**Step 3:**Select the arguments such as**=SUBSTITUTE(A1,”a”,”the”)**

**Step 4:**Press**Enter**key.

We can see that the word ‘a’ is substituted with ‘the’ in cell B1.

Likewise, we can obtain the results using the SUBSTITUTE function.

### Examples

#### Example #1

In the first example, we will substitute the “_” with space in the given set of Name data.

To get the desired output, Tanuj Rajput from Tanuj_Rajput apply the Substitute formula **SUBSTITUTE(A2,”_,” “1)**

It will replace the first instance of “_” with space, and you will get the desired data as output.

#### Example #2

In this example, we will replace the first instance of character “a” with “w” in the given dataset of full names by using the SUBSTITUTE function.

Let us apply the **=SUBSTITUTE(A2,” a”,” w”,1)** formula in the “Formula” column:

As shown in the below table, you will get the output in the “Output” column, shown in the third column.

#### Example #3

In this example, we will replace all instances of character “a” with “w” in the given data set.

By using the substitute formula excel **=SUBSTITUTE(B38,”a”,”w”)**

And drag it in the “Formula” column to the “Output” with no “a” values, as shown in the below table.

#### Example #4

In this example, we will replace all the spaces with blanks from the given set of full names.

Here, we will apply the below substitute formula to achieve this **=SUBSTITUTE(I8,”, “)**

You will get the output without space, as shown in the table below.

### Important Things To Note
