What tool option is used for manually changing data types?

The Select Tool is specifically designed for modifying and managing the data types of fields within a dataset. This tool allows users to easily change the data type of any selected field, whether it be converting a numeric field to a string or altering a date field to another format. It provides a clear and straightforward interface to select various fields and apply data type changes without affecting the underlying data values.

When using the Select Tool, users can also see a preview of the data types currently assigned to each field, making it easy to identify fields that need to be adjusted. This level of control is essential for preparing the data for analysis, ensuring that subsequent processing and analysis steps work as intended with the correct data types.

Other tools listed, such as the Auto Field Tool, are focused on automatically determining and setting data types based on the data’s characteristics, rather than allowing manual adjustments. The Formula Tool is primarily used for performing calculations and transformations on data within specified fields, and the Join Tool is utilized for combining data from different sources based on matching key fields, rather than altering data types.
