Chrome for OS X is lacking a bookmark export feature. I’m sure it will have one in the future, but it doesn’t have it yet. It will happily import your mozilla bookmarks and let you get started using the browser, but eventually you will notice that your bookmarks are locked in. It only recently got a very rudimentary bookmark manager in the latest nightly builds, but there is still no export.
The Chrome bookmark file in OS X is a simple JSON database, so I whipped up a quick tool in Groovy to do the export. This was really a single-use project but I figured I would post the source and binaries in case someone else needs it.
java -jar ChromeExport.jar > mybookmarks.html
By default it will find the current user’s “Default” Chrome profile. Since Chrome doesn’t seem to have any UI for managing profiles, I don’t see why you’d have a different one.
Here is a link to the source: ChromeExport.groovy
Here is a link to the fully bundled binary (which probably breaks somebody’s license agreement somewhere, but compliance is not worth the annoyance): ChromeExport.jar
Enjoy! Let me know what you think, or if it works for you!
