Doing Cookie Import/Export requires third-party extensions to Chrome.
See the article Cookie Import/Export: Quick Guide + Top 5 Tools which lists : EditThisCookie, Swap My cookies, Cookie Editor, Cookie-Editor, Export History / Bookmarks to JSON / CSV / XLS.
You will find in the article a review of each extension.
Chrome stores its cookies in an SQLite database, so a program is required.
The database is found in the file %localappdata%\Google\Chrome\User Data\Default\Cookies.
To import data into this database will require an SQLite database manager, perhaps SQLite itself.
