# Re: formula for getting different sets of data entered

Please try this Array Formula which requires confirmation with Ctrl+Shift+Enter instead of Enter alone.

In C2

``````=IF(COUNTIFS(A\$2:A2,A2,B\$2:B2,B2)=1,
"SET"&SUM(--(FREQUENCY(MATCH(A\$2:A2&B\$2:B2,INDEX(A\$2:A2&B\$2:B2,),0),ROW(A\$2:A2)-ROW(\$A\$2)+1)>0)),
INDEX(C\$1:C1,MATCH(A2&B2,INDEX(A\$1:A1&B\$1:B1,),0)))``````

Confirm with Ctrl+Shift+Enter and then copy it down.

# Re: formula for getting different sets of data entered

In the attached version of @Subodh_Tiwari_sktneer"s solution file, the array formula (confirmed with Ctrl+Shift+Enter) in D2 is:

=IF(COUNTIFS(A\$2:A2,A2,B\$2:B2,B2)-1,
LOOKUP(2,1/(A\$1:A1&B\$1:B1=A2&B2),D\$1:D1),
"SET"&MAX(IFERROR(--SUBSTITUTE(D\$1:D1,"SET",""),0))+1)
