What Split a Number into Digits can do:

This tool splits every valid number into its component digits. You get full control over how they’re separated. If you set the separator to a space, you’ll get clean spacing. Prefer dashes? Commas? It works with anything.

The trim toggle helps remove accidental spacing. If a line isn’t a valid number, you can either show an error or skip it entirely with the Ignore invalid input toggle. A running item count lets you know how many lines were successfully processed.
