The CData Excel Add-In for Pipedrive supports standard SQL joins like the following examples.

Inner Join

An inner join selects only rows from both tables that match the join condition:

SELECT d.UserName, u.Email, u.Phone, u.LastLogin FROM Deals d INNER JOIN Users u ON d.UserId = u.Id

Left Join

A left join selects all rows in the FROM table and only matching rows in the JOIN table:

 SELECT d.UserName, u.Email, u.Phone, u.LastLogin FROM Deals d LEFT JOIN Users u ON d.UserId = u.Id
