Hi SASN,

Enter the following formula in row 1 somewhere, then fill down through row 450:
=INT((ROW()+2)/3)&"_"&SUBSTITUTE(MOD(ROW(),3),"0","3")

If A1 has "1_1", enter following in A2 and drag down

=IF(--RIGHT(A1,1)=3,--LEFT(A1,1)+1,--LEFT(A1,1))&"_"&IF(--RIGHT(A1,1)<3,--RIGHT(A1,1)+1,1)

Shanan,

That will work as long as the first digit is only one character long. Change the LEFT(A1,1) part to include a FIND function to find the placement of the _
=IF(--RIGHT(A1,1)=3,--LEFT(A1,FIND("_",A1)-1)+1,--LEFT(A1,FIND("_",A1)-1))&"_"&IF(--RIGHT(A1,1)<3,--RIGHT(A1,1)+1,1)

Try:

=MOD(INT((ROW()-ROW($A$1))/3),150)+1&"_"&MOD(ROW()-ROW($A$1),3)+1

copied down

you can change the 150 if you are going higher than that
