You can export a .CSV of your Membership Database at any time. This CSV file contains nearly everything we store about your membership, including addresses, phone numbers, emails, child names, any membership notes, etc.
From the Board Member Dashboard -> Members Module, Board Tools section, click Export CSV of Member Data to initiate the download. Check your default downloads folder for the file. It will be named Member-Export-(1).csv. (The number may vary if you have already downloaded the file previously).
