Attached is the VB.NET source code for the Mail Merge Template Creator. Please keep in mind this was developed over 6 years ago as I was introducing myself to the Archer API. I'm very certain there is room for improvements. I'll be very curious to see how others extend or improve the tool, so please share if you do.
NOTE: The tool is not an RSA supported product and is intended as a proof-of-concept for non-prod environments and testing purposes. Archer Support or Engineering teams will not be able to customize or enhance it. Use at your own risk!
