I know. Guess I mainly wanted to say your given solution isn't the entire story and the potential tool should decode the parameters as well, they might or might not be important. I'm often at the computer and I regularly do one-off tasks this way... But I'm aware it might not be an one-off task to you and you might not have a Linux terminal open 24/7 either 😉 Hope some of the other people have what you need. And btw... since I clicked on a few of the suggestions: I think URL encoding is a different thing, that's with all the percent signs and not base64 like here.
