OK I hope you guys can help me out. Here is the scenario. I have 3 spreadsheets. The main spreadsheet I working with has 500 lines with a unique number string. The next two spreadsheets have about 12000 lines but also contain the same unique string as the first spreadsheet. I want to search the 2nd and 3rd spreadsheet using the first spreadsheets unique id number and then take the information from the 2nd and 3rd spreadsheet and then merge it into the first. Does that make since? Any help would be great.
