When you export your data out of Nimble, Nimble generates and emails you a CSV file of all your contacts' information.
The CSV file is formatted to Nimble's CSV template, so that when you have made your updates/edits and are ready to re-import back into Nimble, it will be in a Nimble-ready CSV version!
If you have any questions, please write us at care@nimble.com, initiate a chat from this FAQ, or join one of our Nimble Onboarding and Best Practices sessions, held every weekday at 9 AM PT.
