This extension helps you export your scorecard / log-book from 8a.nu for personal backup or importing elsewhere.
Just install the extension, then browse to your 8a.nu scorecard or log-book, open the extension popup window, and export your data with the click of a button. You can export both your rock climbing and bouldering ascents by using this extension on each of your scorecards.
Files are downloaded in CSV format to the Chrome Downloads folder on your computer. Put this file in a safe place to keep a backup of your 8a data, or use it to import your ascents into another website.
