The Manual:
Save a cantr transcript by copy and paste from your events screen into a pure text editor (notepad is good)
Save as text file.
Double click (in most OS) JAR file.
In first file chooser, bick file to load from (the one you saved)
In second file chooser, pick file to save to.
Done! Look at your chosen output file
If this isn't working, um, bad. Tell me what does happen...
If you mean how... It forms each event into a single string (barring certain freak accidents), puts them on a stack to reverse them, and spits them out into a file.
Note: If you somehow don't have java on your computer, this won't work. I don't know what the minimum version is, but it shouldn't be much...
I was to lazy to make a real GUI for it, but it there is demand I can probably make a graphical application or applet out of it.
