All files are binary. Text files are easily understandable by humans after your favorite text editor transforms the ones and zeros into characters for your viewing pleasure.
You need to know how your binary data is organized, in order to easily read it. For that you could either look for a white paper, ask the person who generated the file, or look at the code of the program that generated the file.
Otherwise you are just shooting in the dark and the chances of correctly reading the file are slim.
