How to Split First and Last Name in Excel: A Comprehensive Guide

As a marketer, I'm always looking for ways to streamline my processes and save time. That's why Excel is such a valuable tool for me. It's versatile, powerful, and can help me complete tasks much faster than I could by hand. One task that I frequently need to complete is splitting first and last names. It may seem simple, but doing it manually for a long list of names can be a real pain. That's why I've put together this guide on how to split first and last name in Excel.

Step 1: Make Sure Your Data is Clean

The first thing you'll want to do is make sure your data is clean. By that, I mean that your data should be consistent and free of errors. Double-check that there are no typos, extra spaces, or other formatting issues. This will make the next steps go more smoothly.

Step 2: Insert a New Column

Next, you'll need to insert a new column. This is where the split names will go. To do this, right-click on the column to the right of the column containing your full names. Select "Insert" and a new, blank column will appear.

Step 3: Use the LEFT Function to Split the First Name

Here's where the real magic happens. Excel has a handy function called LEFT that allows you to extract a certain number of characters from the beginning of a string. In this case, we want to extract the first name. To do this, you'll enter the following formula into the first cell of your new column:

=LEFT(A2,FIND(" ",A2)-1)

Let me break that down for you:

  • A2 refers to the cell containing the full name. Make sure to use the correct cell reference for your data.
  • FIND(" ",A2)-1 finds the position of the first space in the full name and subtracts 1 to get the number of characters in the first name.
  • LEFT(A2,FIND(" ",A2)-1) extracts that number of characters from the beginning of the full name, which gives you the first name.

Now you'll just need to fill down the formula to apply it to all of your names. To do this, select the cell with the formula and double-click on the bottom right corner of the cell. The formula should fill down to the end of your data. Alternatively, you can copy and paste the formula down the column.

Step 4: Use the RIGHT Function to Split the Last Name

Now that you have the first names, you'll need to get the last names. This is a bit trickier, since Excel doesn't have a built-in function for extracting the last word in a string. However, we can use a combination of functions to get there. Here's the formula you'll need:

=RIGHT(A2,LEN(A2)-FIND("*",SUBSTITUTE(A2," ","*",LEN(A2)-LEN(SUBSTITUTE(A2," ","")))))

That might look a little scary, but let me explain:

  • RIGHT(A2, tells Excel to extract characters from the right side of the full name.
  • LEN(A2)- subtracts the length of the full name from the next part of the formula, giving us the number of characters in the last name.
  • FIND("*",SUBSTITUTE(A2," ","*",LEN(A2)-LEN(SUBSTITUTE(A2," ","")))) finds the position of the last space in the full name.
  • SUBSTITUTE(A2," ","*",LEN(A2)-LEN(SUBSTITUTE(A2," ",""))) replaces the last space in the full name with an asterisk, so we can find its position.

Again, you'll want to fill down the formula to apply it to all of your data.

Step 5: Clean Up Your Data

You're almost there! At this point, you should have two columns: one with first names and one with last names. But before you celebrate, it's a good idea to check your data one more time to make sure everything looks right. You may need to manually correct any errors or adjust the formulas if something isn't quite right.


And that's it! With just a few simple formulas, you can split first and last names in Excel. Not only does this save you time, but it also helps ensure your data is consistent and accurate. This is just one example of the many ways you can use Excel to make your life easier as a marketer. Happy splitting!
