The POI Alert bookmarklet lets you export any Google Maps saved list directly to a CSV file, ready to import into the app. Set it up once in Chrome and use it any time you want to bring a list across.
This allows you to maintain your current workflow for adding places that interest you, but importing them into POI Alert when you are traveling or on vacation, so that you are alerted when you are nearby.
Drag this to your bookmarks bar:
Export Maps ListIf your bookmarks bar is hidden, press Ctrl+Shift+B (Windows/Linux) or ⌘+Shift+B (Mac) to show it.
That's it. Dragging it to the bookmarks bar saves it automatically with the name Export Maps List.
