4 Simple Methods to Extract Last Name in Excel

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:

1. Identify the Column:

   • Assume the full name is in Column A, starting from cell A1.

2. Insert a New Column for Last Name:

   • Add a new column next to the full names.

3. 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.

   

4. Press Enter:

   • The formula will extract the last name.

5. 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:

1. Insert a New Column for Last Name:

   • Add a new column next to the full names.

2. Use the Formula:

   =TEXTAFTER(A1, " ")
   

   • " " specifies the space as the delimiter.

   

3. Press Enter:

   • The formula will extract the last name.

4. 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:

1. Type the Last Name:

   • In a new column, manually type the last name for the first row (e.g., "Doe" for "John Doe").

   

2. Activate Flash Fill:

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

   

3. Excel Fills the Column:

   • Excel will automatically extract the last names for the remaining rows.
