Google still doesn't directly let you upload a bookmarks file exported by your browser to Google Bookmarks. Instead, Google recommends to install Google Toolbar in IE or Firefox to upload bookmarks.
Mihai Parparita built a tool for exporting your Delicious bookmarks to Google Bookmarks and it can be used to upload any bookmarks file to Google Bookmarks.
Here's how to do that:
- Go to delicious.com and sign in. If you haven't used Delicious before, you'll sign in using a Yahoo account. If you've previously bookmarked web pages using Delicious, it's probably a good idea to create a new account.
- Unlike Google Bookmarks, Delicious has a bookmark importing feature. Upload the HTML file exported by your browser and wait until all your bookmarks are imported.
- Use Delicious to Google Bookmarks to import your bookmarks to Google Bookmarks. You'll end up with two new labels added by the importing/exporting tools: imported and delicious-export.
