How to extract domain from email address in Excel

In the example, we are using this formula:

=RIGHT(C4,LEN(C4)-FIND("@",C4))

Here’s how the formula works

C4 contains the email address “achang@maaker.com”.

At the core, this formula is extracting characters starting from the right, and using the FIND and LEN functions to figure out how many characters to extract.

LEN computes the length of the entire email address, which 17 characters.

FIND locates the “@” character inside the email address “achang@maaker.com”. The “@” character is the 7th character, so FIND returns 7. The number 7 is then subtracted from the 17, which is 10. The number 10 is used as the second argument for the RIGHT function, which extracts 10 characters from the email address, starting from the right. The result is the domain, “maaker.com”

Altogether, this formula works something like this

=RIGHT(C4,LEN(C4)-FIND("@",C4))
=RIGHT(C4,17-7)
=RIGHT("achang@maaker.com",10)
="maaker.com"
