formula for count unique?

[Danny54]

Is there a formula that counts unique values in a column. I'm creating the data in col a and col b with vba


Existing output

ColA ColB ColC
User1
10.10.10.10
10.10.10.10
10.1.1.1
10.1.1.1
10.4.4.4
blank row
blank row
User2
192.1.1.1
192.1.1.2
192.1.1.2
blank row
blank row




Desired output

ColA ColB ColC
User1
10.10.10.10
10.10.10.10
10.1.1.1
10.1.1.1
10.4.4.4
3
blank row
User2
192.1.1.1
192.1.1.2
192.1.1.2
2
blank row


Thanks

Put the following formula array in B2 and copy down.

Array formulas
Entered with Ctrl+Shift+Enter. If entered correctly, Excel will surround with curly braces {}.
Note: Do not try and enter the {} manually yourself.
