If you want to rename attributes in bulk, which transformer would you use?

• A. AttributeCopier
• B. AttributeManager
• C. DateTimeFormatter
• D. AttributeRenamer

Answer: (D)

Renaming many attributes at once is what the AttributeRenamer transformer is built for. It lets you define a set of old attribute names and their new names, and it applies all those mappings in a single pass as each feature moves through the workspace. Attributes listed in the mapping are renamed, while all other attributes stay untouched. This makes it efficient and consistent when you need to reorganize or standardize many attribute names without changing any of the data values.

Other transformers handle different tasks: an AttributeCopier duplicates values from one attribute to another, a DateTimeFormatter changes how date/time values are presented, and an AttributeManager is a more general tool for modifying attributes but isn’t as direct or streamlined for bulk renaming as the dedicated renamer.
