Hi there! Thanks for getting in touch!
At the moment, we don’t support direct export of events in CSV format with either version of The Events Calendar. Your best bets for native export would likely be our built-in export functionality (which exports to ICS) or WordPress’s own XML export features.
If you do require CSV format for your exports, some of our customers have had good results pairing The Events Calendar with third-party CSV export plugins. We’re not able to provide detailed support for any issues that might occur with these, but it might be an option worth exploring if you’re in need!
I hope that helps! Let us know if there’s anything else we can do for you! 🙂
