As a practical matter, if I read the article correctly, VBA is only going away for the Mac. Is that the platform you're working on? If not, no problem. If so:

1.) Not upgrading sounds good .... it's cheap! 2.) You could move to a PC. 3.) You could learn the beauties of CSV format, and the language of your choice. I like Python, but something else might be better for your domain.

The Larger Issue here, IMO, is the peril of using proprietary technologies. It seems unwise to build any long-term project in something a vendor can too easily end-of-life.
