Is there a free software that can import excel into mysql on mac? not csv format files, but .xls or .xlsx format excel files, is there any free software for mac, that can import data into mysql?
Full disclosure.. I am the author of the following program.
Give it a try and let me know what you think.
I have tried many applications including the excel add-in from MySQL, but was not satisfied with them, so I wrote my own.

The current version of my program is slow (just like the MySQL add-in), doesn't support international characters, and doesn't support command line parameters, but it is free and works well.

I am working on a much better version which will remedy the aforementioned shortcomings and should be available soon.
