While I love having friends who agree, I only learn from those who don't.
This is a simple and working formula. Big thanks for sharing it!
ReplyDeleteI 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!
Yes it does; just apply vlookup command.

ReplyDeleteHey 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.
