Thank you for reaching out.
Apologies for the inconvenience. Unfortunately, at this time, there is no built-in option to import or export data in a Dynamic Content Collection. We understand how important this feature is, especially when managing large amounts of content, and we truly appreciate your feedback.
Please rest assured that we’ve shared this with our development team for consideration in future updates. In the meantime, if there’s anything else we can assist you with, feel free to let us know.
Kind regard
