First thing is you have to run it while EQ is running and have logged in a toon. Once you've done that, bring it up by double-clicking on the icon in the system tray. Click on File | Profiles. Pick a character. Click either Upload or Export.
To know where it exported them to, Click on Options | Setings. Make sure Profiles support is checked and use the button to browse to where you want them stored. The default is the same directory the item collector is installed in. It appears it is still a bit buggy, as I show funky lettering for some of my character names and this is reported in the feedback section. Hopefully you can get it do what you want though.
