Xampp will have phpmyadmin installed.
Type
http://localhost/phpmyadmin (or whatever phpmyadmin is named in your configuration) into your web browser
Log into phpmyadmin with your username and password.
This will connect you to mysql. Choose databases. In the tabs along the top you will see one for imports. Browse to the sql file and hit go.
All should import. If there are any problems with the import it may be because client version of phpmyadmin may be too low for the sql file being imported in which case you will have to run sql file directly from a command line in the mysql client itself.
Try that.
