I have some monthly data in one sheet which I wish to transfer and aggregate
to another sheet at a quarterly level. I couldn't figure out if sumif
function would work here, or is any other methods? E.g.
sheet 1 contains (and continue for many years):
Jan-01 Feb-01 Mar-01 Apr-01 May-01 Jun-01 Jul-01 Aug-01

sheet 2 contains (and continue for many years):
1Q01 2Q01 3Q01

Thanks
