create 2 lists from one

[palaeontology]

Hi all,

I have the following data in the range C1:D15 ...

You'll notice that in the 'Original' column, a student name may appear more than once, which indicates they have more than one parent who supplied an email address (found in column D).

What I would like to do is to have column D converted to 2 lists, resembling the following ...

Parent A	Parent B
melissa.barber@bigpond.com	robert.v.barber@hotmail.com
gaye.grahambell@bigpond.com
alanbw@ccpl.net	bellamywells@hotmail.com
leannebrue@hotmail.com	rodrcsmith@gmail.com
david@propertynorth.com	dee@propertynorth.com
lspence731@gmail.com
mldeeb@bigpond.com
brett.deighton@bigpond.com	jo.hardwick@bigpond.com
nbgreen@bigpond.net.au

<colgroup><col><col></colgroup><tbody>
</tbody>

I'd prefer this to be done by formula rather than code, if at all possible.

Kind regards,

Chris

Hi
if col C and D has the data, insert formula in col. E =if(countif($C$2:$C2,$C2)<=1,D2,"") Drag the formula till the last row.
in col F insert the formula =if(E2="",D2,"") drag till the last row.
Hope that helps
