hi,
i don't know if my solution fits to your problem:
with excel you can save a file as a csv (i think it means comma seperated values) -file.
To import the values from this csv-file to your database use this mysql query:
LOAD DATA INFILE "data.txt" INTO TABLE db.table;
within this command you can tell the database how the values are seperated and if you want to insert the first line in data.txt.
You can find a good description here:
