Go to CRM → Contacts. Next to the + New contact button there is a ⋮ menu — click Export as CSV (N) and you get an instant download of all visible contacts.
The export uses the GHL-compatible format (Contact Id, First Name, Last Name, Phone, Email, Business Name, Created, Last Activity, Tags). Dates are in Europe/Amsterdam timezone. File name: `senly-contacts-YYYY-MM-DD.csv`.
Sales roles only export their own assigned contacts. Admins export everything within the tenant.
