Reading matrices from Excel, CSV or formatted flat files

Hello!

Thanks for your response!

In the meantime, I've written a small Java application, which reads an
Excel file and prints its contents onto standard output, which can be
redirected into a file, readable by Maxima.

It produces files like

<file-contents>
A:matrix(
[16.0,3.0,2.0,13.0],
[5.0,10.0,11.0,8.0],
[9.0,6.0,7.0,12.0],
[4.0,15.0,14.0,1.0]
);
</file-contents>

I'll upload this application during the next few days.

Best regards
