Airodump-ng creates csv files every time you run a scan. But what if you wanted to merge several of its CSV files together and see which access points are contained in both files? Or maybe you want to see which APs and stations are unique to both files?
AiromergeCSV allows you to do this. And you can also include as many CSV files as you want, and it will provide you with a CSV file that shows all of the APs, along with which files they are included in.
You can download it here from my Google drive.
