Which Alteryx tool is designed for data transformation?

The Formula tool is specifically designed for data transformation in Alteryx, allowing users to create new columns or modify existing ones using a variety of mathematical, string, date, or logical functions. This tool gives users the flexibility to manipulate data on a row-by-row basis, effectively transforming the input data to suit their analysis needs. Users can apply complex expressions to derive new values or conditions, making it a powerful tool for enhancing and reshaping datasets.

The other tools mentioned serve different purposes within Alteryx. The Data Cleansing tool focuses on preparing data by removing unwanted characters and handling null values, while the Sort tool organizes data based on specified fields but does not change the data's structure or values. The Join tool is useful for combining data from different sources based on shared fields but does not inherently transform the individual data elements within those sources.
