When trying to convert to uppercase, you need to input exactly "uppercase" Enter a value. This can be useful for things that can only read in uppercase, or lowercase. So when it encounters a value that it can't read, then you can just convert it to upper/lower and then it can read the value. (i suck at explaining lmao) Also, when backpacking this, the lists don't work correctly. So it is recommended to either fill the lists in your own project or import the lists into your project, otherwise this won't really work.
