Hi Celialiu,
A long time ago I did this with a few books, and I succeeded. Importing two books took some time, so perhaps Calibre is busy with the jobs and you think nothing happened. You can see the jobs in the bottom right corner. Or do you get an error message?
Actually I scanned the barcodes in the Goodreads app, exported it to a file, and imported it with copy/paste into Calibre.
I made a little blog about it, but it is in Dutch.

Hope this helps.
