Count characters in contact names from a CSV while retaining the original data. Reuse, update, reset, inspect, and download the structured result.

Counts the characters in each name in an uploaded contacts CSV. The reusable Name Lengths transform retains the original name and email columns, adds a name_length column, and produces inspectable, downloadable structured data. It supports updating the existing transform to also count email characters, resetting generated results while preserving source materials, and recreating a clean default result without duplicates.
