You can run a statement like this:

SELECT col1, col2, col3
 FROM `your-db`.`your-table`
 INTO OUTFILE 'C:/data.csv' 
 FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\r\n'

You should be able to open the CSV file with Excel without problems.

If you want to have this done automatically, you can create an event on your MariaDB server:

CREATE EVENT `automatic_export`
    ON SCHEDULE
        EVERY 1 DAY STARTS '2022-01-20 12:00:00'
    ON COMPLETION PRESERVE
    ENABLE
    COMMENT 'Save Table to CSV for Excel'
    DO BEGIN

    SELECT col1, col2, col3
     FROM `your-db`.`your-table`
     INTO OUTFILE 'C:/data.csv' 
     FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\r\n';
END

It is important to check that the event scheduler is activated for events to work. So you must add the following line to your my.cnf :

[mariadb]
...
event_scheduler = ON;

See: https://mariadb.com/kb/en/events/

With this solution you won't need any external tools for your automatic export.
