I have a two columns A with surname and B with first name, but entered
multiple times:

eg:

Smith, John
Smith, John
Smith, Arthur,
Rabbit, Peter,
Rabbit, Peter
Rabbit, Peter

What's the easiest way to total up the number of people there are? In
this case 3.

Thanks

Try this:-

=SUM(IF(FREQUENCY(IF(LEN(A1:A10)0,MATCH(A1:A10,A1 :A10,0),""),IF(LEN(A1:A10)0,MATCH(A1:A10,A1:A10,0 ),""))0,1))

It;s an array so Ctrl+Shift+enter

I missed they are in 2 columns so concatenate them into a single column first

in C1 =A1&B1

Apply the formula to the concatenated column.

one way:

InC1: =A1&B1 and copy down

in D1: =SUM(1/COUNTIF($C$1:$C$6,$C$1:$C$6))

Enter with Ctrl+Shift+Enter
