Hello there! I made an extremely lightweight, fast and customizable numeric encoder/decoder, that is only one sprite big and is case-sensitive! It's made with only 79 blocks and is one sprite, so it's easily backpackable! The output of the function is in the variable "output". You can even add more letters by going to the costumes and making a new costume! It works with all lengths! All code is made by myself, and please give credit when you use it, thanks ♥️ Average time is less than a millisecond (test script is included!)
