This addon will loop through all of your statistics (Shift-Y) and export them all as either a plain text list, or an HTML page that acts much like the statistics UI, with working tabs and everything.

Commands:

/stats [v/ver/vers/version] - Display current AddOn version.
/stats - Print command help
/stats help - Print command help

/stats html - Shows a text box with all of the HTML code ready to paste into a document and save.
/stats text - Generates a plain text list without any HTML or anything.
/stats text2 - Same as text, but lines up the values column, and shortens some looong statistic names
/stats csv - Generates comma separated values list, for use in Excel or the like

The code will take a few seconds to generate, so don't fret if it looks like WoW just froze. You can change most (if not all) of the looks in the <style> block at the top of the code.
