[Maxima] How can i export Data to Excel file?

[Sara Pashmineh]

Hello,

I tried to use the command: appendfile (filename) for exporting data
from Maxima simulation which I want to use, calculate and plot with
another application tools like Excel or Matlab.
Unfortunately I can not open the crated file in Matlab or Excel.

Has anybody an idea, how I could export data from Maxima and import it
in Excel, Matlab or another application tools?

Many thanks in advance,

Sara
