To export your members' data, go to the Member Directory and click the gear icon next to the search bar:

Click the file format you'd prefer and your file will automatically start to download. 

Pro Tip: Once exported, use the ID column to get the Mobilize Member ID.  This can be used with our API or Zapier to update member information or (if a group manager) be used in the

sender_id 

field when using the send group invite call with the API.
