Question: Export data to excel file


I have a problem to export datas in an excel file.

I have no problem to read some datas in this file, but when i want to write a matrix 1x1 in a cell, there is no error message but nothing happen in the file.

Here is my program :



File1 := FileTools:-JoinPath(["Excel", "test.xlsx"], base = datadir);
Mat1 := Import(File1, "Somme", "G2:G8"); # it runs very well
R := array(1 .. 1, 1 .. 1, [[564]]);
Export(R, "test.xlsx", "Somme", "G1"); # nothing happens in the file

Thank you very much for help
