I have over a thousand individual Excel files which contain data that I
would like to import into a MySQL database. Can anyone recommend an
efficient way I can achieve this?

I know that I can individually save each Excel file as a .csv file and
import that into MySQL but this is going to take me too long with the
number of files involved. What is the quickest way to "batch convert"
multiple .xls files to .csv? Ideally I would be able to convert
multiple .xls files to a single .csv file.

Is there a command line that I could run, something along the lines of:

c:\spreadsheetsexcel save *.xls *.csv
or
c:\spreadsheetsexcel save *.xls consolidated.csv

Any help and advice gratefully received
