Short description of Groovy Hex Editor 1.6: Groovy Hex Editor is a tool for editing binary formats. I' ve paid particular attention to making it colorful and easy to use and tried to give it a cool looking color scheme (hence the name " groovy" hex editor). It' s a fully functional hex editor with many advanced features. You can toggle the display between hex and decimal, and there is a built in inspector that easily lets you see the hex, decimal, and binary equivalents of a group of bytes.
