Image Write in Excel

Hello all,

I am trying to write image pixels values in excel file, the size of image 2048x1365 uint8. presently using windows 10. It seem small issue, but stuck last 10 minutes.

ver: Matlab 2017a

im=rgb2gray(imread('coolerdarker.jpg'));
xlswrite('Test1',im);

#Error:

Error using xlswrite (line 226)
The specified data range is invalid or too large to write to the specified file format. Try writing to an XLSX file and use Excel
A1 notation for the range argument, for example, ‘A1:D4’.
Error in matlab_test_file (line 16)
xlswrite('Test1',im);

Thanks

Xls files support only 256 columns. You need to switch to xlsx files.
