Excel: How to Extract Domain from Email Address

You can use the following syntax to extract the domain name from an email address in Excel:

=TEXTAFTER(A2, "@")

This particular formula extracts the domain name from the email address in cell A2.

For example, suppose cell A2 contains the following email address:

This formula will return just the domain name from this email address:

The following example shows how to use this formula in practice.

Example: Extract Domain from Email Address in Excel

Suppose we have the following column of email addresses in Excel:

Suppose we would like to extract the domain name from each email address in column A.

We can type the following formula into cell B2 to do so:

=TEXTAFTER(A2, "@")

We can then click and drag this formula down to each remaining cell in column B:

Excel extract domain name from email address

Column B now contains the domain name from each email address in column A.

For example:

The formula extracts statology.org from zach@statology.org
The formula extracts superemail.com from doug@superemail.com
The formula extracts messengerflighter.com from cody@messengerflighter.com

And so on.

The TEXTAFTER function in Excel extracts all text in a cell after a specific character or substring.

This function uses the following syntax:

TEXTAFTER(text, delimiter, [instance_num], [match_mode], [match_end], [if_not_found])

where:

text: Text to search
delimiter: Character or substring to extract text after
instance_num (optional): Instance of delimiter after which to extract text (default is 1)
match_mode (optional): 0 = case-sensitive (default), 1 = case-insensitive
match_end (optional): Treat end of text as delimiter (disabled by default)
if_not_found (optional): Value to return if delimiter is not found

Recall that we used the following syntax to extract the domain name from each email address:

=TEXTAFTER(A2, "@")

By using a value of @ for the delimiter, we were able to specify that we wanted to extract the text after the @ in each string.

This is equivalent to extracting just the domain name from each email address.
