Which Alteryx tool can be used for blending data from multiple sources?

The Join tool is specifically designed to blend data from multiple sources by combining two datasets based on a common key or common field. When using the Join tool, you can specify which fields from each dataset to match against each other, allowing for a precise merge of information. This is essential for operations where you need to integrate different datasets that share some shared attributes or keys, thereby enabling comprehensive analyses.

While the Summarize tool performs aggregations and calculations on data, it doesn't blend data from multiple sources in the same way that the Join tool does. The Union tool is used to stack datasets vertically, meaning it works well for combining similar records from multiple sources, but it doesn't join on common fields. The Batch Macro tool serves a different purpose by allowing for the repeated processing of data, typically for scenarios that require looping through sets of inputs but does not directly relate to blending datasets.
