The .exe is actually a self extracting ZIP file. You can open it with WinZip and extract the XLS from there without running the self extractor. However, you can also download a straight ZIP file from here. This is actually about 70K smaller as it does not contain the self extractor code.

Note that the spreadsheet contains macros. These are needed to do the downloading of the currency translations and the sorting of the fares. They are not protected so you can read them (assuming you speak Visual Basic) to see that I'm not trying to erase your hard drive or do other dastardly things to your PC.
