I have written a little script that converts the raw text file from the course website and gives you a file with comma separated values. CSV files can be opened by any old spreadsheet program. It has the added bonus of converting the RTT from scientific notation to normal decimal numbers. The script is written in Python so you need to have that installed; OS X and Linux will have it out of the box. If you have Windows and don't want to install Python you can use the lab computers at UCL. The script is here. Download the .py file in the same directory as the coursework .txt and then run
python txt2csv.py <yourinputfile.txt>This should create a file called coursework.csv. If you find a bug please stick it in the comments.
