I need a software/application that can check the certain email addresses in an excel file against another excel file. The user would load the file A containing the email addresses in that software and then load another file B of email addresses and run the software. The system would read all the email addresses mentioned in file B and then check them against the email addresses in file A. If any of the email addresses present in file B are also present in file A the system will delete those email addresses and confirm the user that x number of emails are being deleted and then save the file. It is a simple application that can be made in Microsoft Access or any other program.
