# Excel Functions LEFT, RIGHT, MID, and LEN for Substrings

Have you ever needed to get the first and last name from a full name? Or maybe pull the street name from an address? 🤔

Tasks like these are easy!

But when you have hundreds or even thousands of lines of data, well…

…things become absolutely tedious! 😱

Lucky for us, Microsoft Excel provides the LEFT, RIGHT, and MID functions.

In this Excel tutorial, you learn to turn this…

…into this!

You also learn how to unlock their full potential using LEN and FIND!

**Table of Contents**

Let’s dive right in!

Open practice workbook.

You’ll find the *Contact Names* and *Contact Numbers* of several people.

This could be a list of potential customers of a business. Or, a list of teachers’ contacts for students.

Information like this is usually split up into smaller bits for use in typical applications.

For example, you might need the *Area Code* for each contact.

To get this, you use the LEFT function.

## Extract text string using the LEFT function

The LEFT function extracts a given number of characters starting from the left side of a string.

1. Type “=LEFT(” in cell C2 where you want the first *Area Code*.

2. The first argument of the LEFT function is** text**, this is the source text string.

Typically, this is the cell reference and in this case, it’s **B2**.

So, type:

**=LEFT(B2**

And put a comma to separate the next argument.

3. Next input is **num_chars**. This is the number of characters from the left of the string that will be extracted.

If you count the characters of the Area Code including the parentheses, you get 5.

So, input 5 and close the formula with a right parenthesis like this:

**=LEFT(B2,5)**

4. Hit Enter.

5. Let’s fill up the rest of the rows by double-clicking or dragging down the **fill handle**.

**Result:**

Great work!

Now, you need the Extension number and you can get this using the RIGHT function.

## Extract text string using the RIGHT function

The RIGHT function extracts a given number of characters starting from the right side of a string.

It has the exact same arguments, **text** and **num_chars**, as the LEFT function.

1. You want the first *Extension* number to appear in cell D2, so, type “=RIGHT(“.

**Pro Tip!**

Excel automatically suggests formulas as you type.

For example, you can just type “=ri” and the suggestion for “=RIGHT(” will appear.

Press the** Tab** key to input the suggested formula.

2. Next, input the first argument which is still cell B2.

**=RIGHT(B2,**

3. Then, count the number of characters from the right to get the Extension.

You get 3, so, your formula should be:

**=RIGHT(B2,3)**

4. Hit **Enter** and fill in the rest of the rows using the fill handle again.

**Result:**

Alright!

But what if you need text from the middle part? Like the *Landline* number in this case.

For that, we have the MID function.

## Extract text string using the MID function

The Excel MID function extracts a given number of characters starting from a specified position within the source string.

1. The first* Landline* number should appear in cell E2. So, type “=MID(“.

You can hide Column D.

2. The MID function has the same first input as LEFT and RIGHT which is the source **text**.

So, the formula becomes:

**=MID(B2,**

3. The second input in the MID function is **start_num**.

This is the starting position from where the substring will be extracted.

Let’s count each character in the *Contact Number*:

Type this into your formula for the **start_num**:

**=MID(B2,7,**

3. The third input of the MID function is** num_chars**. This is the number of characters from **start_num** that will be included in the output substring.

From the character count shown above, you know that the last digit of the* Landline* is at position 14.

This means the whole* Landline* number consists of 8 characters.

So, your formula becomes:

**=MID(B2,7,8)**

4. Hit **Enter** and fill in the rest of the rows.

**Result:**

Nicely done!

You now know how to use the LEFT, RIGHT, and MID functions!

These functions are often combined with other Excel functions to produce more complex formulas.

Let’s take a look at some examples below.

## Extract substring before or after a specific character

Now, take a look at the *Contact Names*.

We can use LEFT to extract the *Title* used for each person.

However, since “Mr.”/”Ms.” and “Mrs.” have different string lengths, we have to input** num_chars** dynamically.

If you’ll notice, the period symbol “.” is common to all titles.

You can use this as the **delimiter** which indicates the string length needed.

It’s now just a matter of finding that delimiter in a given text! 🔎

### Example 1: Using the FIND function

The FIND function returns the position of a specified text within another text string.

1. The first *Title* should appear in cell F2. So, type “=FIND(“.

2. The first input in FIND is **find_text**. This is the character or delimiter that you are looking for.

Since we are looking for the period symbol, type:

**=FIND(“.”,**

3. Next input is **within_text** and this is the source string.

In this case, it is cell A2. So, the above formula becomes:

=FIND(“.”, A2

The third input is

start_num. This is the starting position where Excel will look within the source string.This input is optional and by default, FIND scans a string from the very beginning at the left.

4. Hit **Enter**.

5. Now, use the above FIND function as the second input in the LEFT function.

Your formula becomes:

**=LEFT(A2,FIND(“.”, A2))**

6. Hit** Enter** and fill in the other rows.

**Result:**

The SEARCH function can also be used similarly. But it is not case-sensitive, unlike the FIND function.

Also, you can use any

symbolin the FIND function as we’ll see in the next example.

### Example 3: Combining FIND functions

Next, you want to extract the* First Name*.

This is not as straightforward as the above examples. To do this, you first have to understand the concepts below.

Let’s get to it!

You know that the* First Name* is between the first and second spaces ” ” which are in positions 4 and 10 respectively.

To get the *First Name*, you can use MID to extract characters starting from position 5 (character immediately after first space) up to position 9 (character preceding the second space).

But how exactly do you type the formula?

1. Getting the starting position for the MID function is easy enough.

You use **FIND** just as in the previous example. But instead of the period symbol, use the** space character** ” “.

Also, add 1 to the result. The starting position formula becomes:

**=FIND(” “,A2)+1**

Try this in cell G2.

2. To get the position of the second space, you need to use the third input of the FIND function which is **start_num**.

You know that the position after the first space can be given by:

**=FIND(” “,A2)+1**

You can then use the above formula as the **starting position** of the second FIND function to find the second space like below:

**=FIND(” “,A2, FIND(” “,A2)+1)**

Try it out in cell G2.

3. Now, you can combine the above formulas to express the string length input in the final MID function in cell G2.

Your MID formula is basically:

**=MID(A2, position AFTER 1st space, position of 2nd space – position of 1st space – 1 )**

So, the final formula in cell G2 will be:

**=MID(A2,FIND(” “,A2)+1,FIND(” “,A2,FIND(” “,A2)+1)-FIND(” “,A2)-1)**

You deduct 1 at the end to remove the extra space from the result.

4. Fill in the rows below and watch Excel magic happen!

Incredible, isn’t it? 🤩

There’s one more interesting example below!

### Example 3: Using the Excel LEN function

Finally, if you want to extract the *Last Name*, you use the RIGHT function.

Going back to the character count, you know that the *Last Name* is just the characters from the right of the *Contact Name* up to the second space.

This length can be expressed as the length of the entire text minus the position of the second space.

You already know how to get the position of the second space from the previous example.

So, how do you get the length of the whole text string?

You can use the **LEN** function to get the length of any input string.

1. In cell H2, type the formula below:

**=LEN(A2)**

2. Now, you can combine this with the formula for the second space to get the length of the *Last Name*:

**=LEN(A2) – FIND(” “,A2, FIND(” “,A2)+1)**

3. Finally, complete the RIGHT function by using the formula above as the number of characters to be extracted:

**=RIGHT(A2,LEN(A2) – FIND(” “,A2, FIND(” “,A2)+1))**

4. Hit **Enter** and fill in the rows below.

**Result:**

Congratulations! 👏

You have completed the practice workbook!

## That’s it – Now what?
