Remove duplicates from CSV files in a flash with an AutoHotKey script

Remove-DuplicatesIn email marketing I am frequently having to remove duplicates.   I typically used Excel for this but I did it so frequently I built a small script to automate the process.

The program requires a CSV file and utilizes Microsoft’s Component Object Model to open Excel and examine the headers for a field named “email”.  Once it finds it it removes duplicate email addresses and saves them as a new file in the same folder with the naming showing how many rows are present.   This greatly reduces the amount of work needed to do the job.
This should ease the removal of duplicates from CSV files.
