D-MAPPER

D-MAPPER grew out of a simple requirement: replace real values with sanitized ones without losing the ability to reverse the process later.

Instead of doing the same search-and-replace work over and over, I can define mappings once, switch from Real → Sanitized, work with the sanitized data, and then map Sanitized → Real when I need the original values back. Rule sets, regex matching, and per-rule toggles make the workflow useful beyond a handful of static replacements.

Everything runs locally in the browser. The mappings and UI state can stay on the machine, which is exactly where I want this kind of utility to live.
