Create email address with name and domain

Excel formula: Create email address with name and domain
Generic formula 
=LOWER(LEFT(first)&last&"@"&domain)
Explanation 

To build an email address from a first and last name, you can use a formula based on simple concatenation with help from the LEFT and LOWER functions.

In the example shown, the formula in D5 is:

=LOWER(LEFT(B5)&C5&"@"&$G$6)

How this formula works

Working from the inside out, this formula first concatenates the last name in column C with the first letter of the first name from column B:

LEFT(B5)&C5

The LEFT function is normally configured with num_chars, but the argument is optional and left will extract 1 character from the left when it is absent. This results in the text string "atanaka".

Next, the domain name is added like this:

"atanaka"&"@"&$G$6

Note that the reference to the domain name is absolute ($G$6) so that the formula can be copied down the table without this reference changing.

Finally, the lower function is used to lowercase the entire string:

=LOWER("ATanaka@acme.com")

which returns a final result of "atanaka@acme.com"
