There are two separate reports as two separate Excel file. The old one is on a server and the new one is pulled once each week from a system where data is updated all the time. Column G is added to the new report as a Insert Column function.

However, 100s of new rows are added each week. So the old report will not be having those new rows actually.

The logic necessary to populate G column on the new report is - "If the respective cells for column A, E, F and H in last report and new report ARE THE VERY SAME, what ever was there in the old report in the Column G in that row should get populated in the new report Column G. Otherwise it should be populated with blank."

This means all newly added rows should be populated with blank in the G Column of the new report.

I am looking for some Macro or Merge or any other type of Formula that can be used in this case but VLOOKUP will not work in this case. Any suggestions or guidance would be highly appreciated. I also must say that it is impossible to do this manually as there are more than 6000 rows in the reports.

VLOOKUP to Left?
Use =VLOOKUP(A2,CHOOSE({1,2},$Z$1:$Z$99,$Y$1:$Y$99),2,False) to lookup Y values to left of Z values.
