If you have full names in a single column and want to extract just the last name, Excel provides various methods to do so. Here’s a tutorial to help you get it done.
Method 1: Using the RIGHT and FIND Functions
This method works when the full name is in the format "First Last."
Steps:
-
Identify the Column:
- Assume the full name is in Column A, starting from cell
A1
.
-
Insert a New Column for Last Name:
- Add a new column next to the full names.
-
Use the Formula:
=RIGHT(A1,LEN(A1)-FIND(" ",A1))
FIND(" ",A1)
locates the space between the first and last names.
LEN(A1)
calculates the total length of the name.
RIGHT
extracts the text after the space.

-
Press Enter:
- The formula will extract the last name.
-
Copy the Formula Down:
- Drag the fill handle down to apply the formula to the rest of the rows.

Method 2: Using the TEXTAFTER Function
The TEXTAFTER function (available in Excel 365 and Excel 2021) simplifies extracting text after a specific character.
Steps:
-
Insert a New Column for Last Name:
- Add a new column next to the full names.
-
Use the Formula:
=TEXTAFTER(A1, " ")
" "
specifies the space as the delimiter.

-
Press Enter:
- The formula will extract the last name.
-
Copy the Formula Down:
- Drag the fill handle down to apply the formula to the rest of the rows.

Method 3: Using Flash Fill
Flash Fill is a quick and easy way to extract last names without formulas.
Steps:
-
Type the Last Name:
- In a new column, manually type the last name for the first row (e.g., "Doe" for "John Doe").

-
Activate Flash Fill:
- Select the next cell in the column.
- Go to Data > Flash Fill, or press Ctrl + E.

-
Excel Fills the Column:
- Excel will automatically extract the last names for the remaining rows.
