In Alteryx, what function does the Union tool serve?

The Union tool in Alteryx is utilized to combine multiple data streams into a single output. This is particularly useful when you have different datasets that may share some common fields, and you want to consolidate them into one cohesive dataset for further analysis. The Union tool allows you to stitch together rows from various inputs, making it easier to work with larger sets of data that may originate from different sources but are relevant to the same analysis.

When you employ the Union tool, it matches the column names from the input streams and stacks the data vertically, resulting in a unified dataset. This functionality is essential in data preparation workflows, where merging data from multiple tables or files is often required to create a comprehensive dataset for reporting or analytical purposes.
