I'm not sure I understand your needs. If you just want to backup your bookmarks and restore them to another machine, what's wrong with the built-in export/import options?
I'm pretty sure Chrome allows you to backup and sync your bookmarks across your Google account if you login to the browser itself.
Or you can also do it manually. I use Brave, which is based on Chrome, so it should be something like this:
- To export: Press Ctrl-Shift-O to open the built-in Bookmarks Manager ( chrome://bookmarks/ ). Then click the three-dots menu and select Export bookmarks.
- To import: Click the hamburger menu and go to Bookmarks, then select Import bookmarks and settings (which should take you here: chrome://settings/importData ), then select Bookmarks HTML File from the dropdown list, and select the file containing your exported bookmarks.
