I need to be able to filter by subaccount and export as CSV file

The numbers I am finding in the database are off by a few dollars despite having the same number of leads over the same time period. I would like to compare the Lead ID's in my database to check the values. This would be very time consuming the way this report is presently. if I could filter based on subaccounts and export the results as a CSV. I could run a query easily and compare the values.
