This is a simple and working formula. Big thanks for sharing it!

I wonder if Excel can match two data sets too by a common column? e.g.: data on species abundances with data on species traits.

Keep on good work Deepanshu Bhalla!

Awesome!
Very nice work, needs some explanation to get to know the real engineering behind these commands. For example what it actually does for "Multiple consolidation ranges" etc.
Still its great as it works.

Hey How does this work if we have 6 more dates say end date consider the date column in your example as start date. so basically we have 2 sets ( 6 each) of columns.
