In Alteryx, what does the Append Fields Tool do?

The Append Fields Tool in Alteryx is designed to enhance a dataset by adding additional fields from another dataset. This functionality is ideal when you have a primary dataset and you want to include extra information from another dataset without changing the overall structure of the primary dataset. Instead of merging or joining datasets based on a key, which would combine records into a single row with matched fields, the Append Fields Tool allows you to append new columns from the secondary dataset to every row of the primary dataset. This is particularly useful for enriching data with supplementary details that are not directly related to the key fields but are relevant to the analysis.

By using this tool, users can create a more comprehensive dataset for reporting or analysis purposes, effectively increasing the richness of the data without altering the relationship structure that would be involved in a merge or join operation.
