So as a map maker, commands aren't always easy , so we use generators to both simlify the process and speed things up. I've recently came across a website called minecraft.tools which offers all kinds of tools & I immediately fell in love with the site. I quickly coded an application that takes you to that website and doesn't let you go on specific site like google and so on. If anyone wants a copy then feel free to download this application.
Note: I've developed this for personal use only. I'm only releasing it for people who make lots of minecraft custom maps and stuff of similar agenda
