## Description

A lightweight utility for cleaning and reformatting lists of numbers. Paste or drop a raw list in any format (comma, space, or newline separated), set a minimum digit threshold, and the tool filters out invalid entries, removes duplicates, and sorts the result. Output can be copied or saved in five formats: one-per-line, CSV, space, tab, or pipe separated. Rejected entries are logged by category for review.

This was created for personal use originally, but I've decided to share in case this helps anyone else.
