Will be using vapi to call clients and get data feom them. Have the data schema setup, it saves the data per call in the analysis. How can i import this data in my csv or excel lead list with a new column for this new data i received?

Match it to your lead list using a common identifier like phone number, and add the new data as columns manually in Excel or automate the process with tools like Zapier, webhooks, or database integrations.

If i have a name for the lead, can vapi see the name on csv and say hello (name)? And confirm the phone nmber they are calling?

Yes, you can pass lead names and phone numbers from a CSV as variables, allowing the assistant to greet callers personally and confirm their phone number during the call.
