Any way of mass data dumps in excel? Or Automation?

I am pulling general ledger data for my company for an IRS audit and our sales company has almost 500k lines of entries each day and I’ve pulled all of that out of sap but the problem is. I had to pull two separate reports for each and now I need to combine them.

I’ve done it for the smaller companies and just compiling and sorting with a query takes an hour each. Have no other idea how to get it quicker. Looking for any tips
