Hey guys i'm glad to be here around all of those excel pros!

Have been doing data extraction from one of my competitors, in an daily basis, where they have declared the stock values of their products..
What i'm trying to do is to compare all the sheets based on the url by identify the urls along with the stock values, in that way i can devide the stock values to see their actual sales.

Not realy sure if i should use the VLOOKUP function, so i get the right comparsion and from there divide the results to find out the actual number of sales.
Or if i'm should making an formula.
It may happend that those sheets does not showing the same order, so i have to specify what the coulmns in order to getting proper results, thats why i'm were thinking about the VLOOKUP.

I'm an total noob of excel but trying to learn
