Choose if you want to convert from URL to the word, or the word to the URL. If it asks for the URL don't put the URL in full, just the gibberish after the "Word=" in the URL like this https://mywordle.strivemath.com/?word=nwtnlwpzvb all you would put is "nwtnlwpzvb" When it asks for the word you should just put the word, it can be a made up word as well, like "vulhpoxxnv" you can use it to cheat at custom wordle and confuse your friends
To find out how to convert the code, I basically got things like "AAAAAAAAAAAAAA" which came out as wordle a few times, then found it out for the rest of the letters, I made a few typos but found out the it goes to the next letter for each of the 6 letters it converts.
