Hey Guys
I am working with a very large data set (over 10, 000 columns).
There are 100 unique values.
I have the latitude, longitude and altitude for 100 locations.
I want to add this information to my large dataset.
Basically I want to fill column B, C, D based on the value of column A.
But I have over 100 different options so need a fast way to do this please.
Thank you
