Comparing data in large excel list

Hi,

I have three large worksheets containing data from three different tools. The tools are used to manage equipment lists. And the list keeps changing everyday with both additions / deletions.

Worksheet 1 has about 1.3 mn rows, Worksheet 2 has 1.6 mn rows and lastly Worksheet 3 has ~ 650 K records.

All the files have multiple columns but I am interested in comparing the only the first two columns which are Asset Tag and Serial Number. I need to know the number of equipments available in all the three lists first by Tag # and from the balance list, need to know how many match by Serial #.

while I can do this by vlookup / match+index, it would be time consuming and moreover WS1 and WS2 data go beyond the excel limitation of ~1.1 mn rows.


is there a workaround / different way to do this ?
 
I'd recommend Microsoft Access or another database program. They are much better at handling extremely large data sets.

If going the Access route, see if your tools have the capability to interface with Access automatically or on demand, and then you can build queries against the database to get the results you need.
