After a six-year hiatus, we are pleased to announce SumProduct has managed a return visit to Microsoft’s Excel blog. We note fellow Excel MVP Ingeborg Hawighorst has also posted too, so we’d like to pass on our congratulations to her too!

Back in 2013, we posted what became the fourth most visited page of the year (on Multiple Multiples) – so it’s nice to be back! To celebrate, we thought we’d post the new and the old here too, for posterior / posterity!
