Using a regex expression seems like a good bet.
\[(.*?)\]
This is still going to be page by page in a text editor but faster than manually deleting them in the WP admin UI.

Hi, I just updated to version 1.3 using the worpress updater and now I’m unable to view my custom sidebar at all. This error code is appearing in my sidebar:
Fatal error: Call to undefined function dynamic_sidebar() …
Additionally, my widgets page is totally non functional. Dragging no longer works and no sidebar regions appear.
Deactivating the module and replace widgets.php seems to resolve the issue.
