Key Features & Functionality
FWIW, for anyone who's primarily interested in simple base64-to-text or text-to-base64 conversions, I wrote both expression rules using all-OOTB functionality a few years ago and left them both in this thread. They have no hard-capped length limits, though testing yesterday with an input string of 10,000 characters I realized that anything much longer is likely to lead to (momentary) performance implications.
