Convert Keeper CSV exports to Lastpass CSV import

gistfile1.txt

This isn't 100%, but it will get you most of the way there (assumes bash 4+):

(\
    echo 'url,type,username,password,hostname,extra,name,grouping' ; \
    cat KEEPER_BACKUP_FILE | sed -e s/'     '/'|'/g -e s/','//g | (\
        while read LINE; do \
            IFS='|' read -r -a fields <<< "$LINE"; \
            type="server"; \
            if [[ "${fields[4]}" == "" ]]; then \
                type=''; \
                fields[4]="http://sn"; \
            fi; \
            echo "${fields[4]},server,${fields[2]},${fields[3]},,${fields[5]},${fields[1]},${fields[0]}"; \
        done\
    ) \
) > SOME_NEW_FILE.csv

You will need to manually go through the CSV this generates, it is not accurate enough to trust it 100%. But it will get you going.
