Add data to your dataset by pulling in additional data from an external data source.
Datasets are frequently missing certain columns that you want included. For example, your table of leads may have a country but not a region. If you come from Excel you may be worried you have to figure out how to write a VLOOKUP function and constantly make sure it's correctly dragged down to all cells.
Assuming you have a list of countries and their associated regions you can use a “Join” object to map the region data to your existing company list using the company column as the common field. The resulting data will have a region column for every entry.
