I have two excel files. They are filled out with numbers and text. The first file has 6 columns, say (a, b, c, d, e, f), while the second file has one column called "g" in addition to some similar columns like (a, b, c) , i.e, second files has 4 columns (a, b, c, g).
I would like to go through each row of the second file, figure out it is equivalent with which row of the first file (which row in the first file has the same values in columns (a, b, c)), and then add the value in column "g" to the first file and generate a new excel with 7 columns (a,b,c,d,e,f,g).
Any input would be greatly appreciated! Thanks!
