Ahh that's great thanks for your help leafo! Yeah I was using windows notepad to view the keys.
In case anyone else has the same issue; to get the keys in a nice format, open up excel then File -> Open and set the little drop down to be "All files", so you can see the generated .txt file with all the keys in. Then follow the on screen prompts about formatting. Default settings on these worked for me. Then there you have it nice and easy to read on separate lines!
