I need to convert a large number of record in excel to the mysql database, what should I do?
I had find some software, but it cost about HK$100
did there is any other method to change the excel record in mysql database?

I'm not sure exactly what you're wanting to accomplish ... however, if you're wanting to take the data in an Excel spreadsheet and insert it into a MySQL database, that should be pretty easy to do with Perl. There are plenty of modules which will allow Perl to do this.
