Hi, I'm new with this stuff, but I have to charge an excel matrix in arduino. This matrix is in excel's format. I can't work with SD Cards, I´d prefer the serial communication, so, when I run the debuger, the program extracts the matrix from the PC, but I don't know how to do it. Also, when I have charged the excel matrix, I select a value from the first column, and automatically the program's equations work with different values form the row of the initial selected value.

You aren't going to do it on an Arduino. You can do it from an Arduino.

What debugger? What program?
but I don't know how to do it.
Too many details left out for us to help you, either.

You charge batteries and capacitors, not spread sheets. What do you want to do?
