You're going to need to export the data into a database, which as a feature hasn't been used in a while.
Go to the options window and click on "recording". At the bottom, "enable database recording" and give your database a name. Everytime a bot dies, its information gets logged into the database.
The database itself is a comma delim'ed database, which is a sort of general purpose text based database that different spreadsheet programs should be able to import.
If you need more specific features, or the database doesn't work anymore, Eric or I can probably strap in what you need without too much difficulty.
