How can I import Opera bookmarks into Chrome?
Export bookmarks from Opera as a HTML file (menu File/Import and Export/Export Opera bookmarks).
To import into Chrome, open a new tab and type chrome:bookmarks. This will display a page that is not accessible from the customize 'spanner' menus.
You will see an organise tab with a drop down menu. The last options are import to and export from HTML file.
There is no need to use third-party software to 'translate' bookmarks any more.
I found bug trying export Opera bookmarklets into Chrome : Opera bookmarklet should not be contain empty folders and folders without name (otherwise while Chrome stops importing process after empty folder / folder without name position)
So 3 steps migrating Opera bookmarks to Chrome:
Check and delete Opera bookmarks for empty folders / folders without name (this applies Trash folder too - so clean it up)
Go to Opera menu button - Settings - Import and export - Export bookmarks as HTML (choose file name and location)
Open Chome's Bookmark Manager (Ctrl+Shift+O), find Organize menu - Import bookmarks from HTML file... (and locate Opera's exported file)
Opera 35.0 appears to have no Import/Export option under settings, and they have deactivated Opera Link, so there is no way to do this except through other 3rd party software. Transmute does not appear to work.
As far as I remember, Chrome installer has no Opera bookmarks import feature (supports only I.E. and probably Firefox). Try to use Transmute -- this tool supports all major browsers (without intermediate exporting the bookmarks to HTML from the browser) and some other formats. In addition, it features some other handy stuff which you may also be interested in.
