Thanks for your quick response.

>>If you are you trying to open the Excel document via a browser https://fastapi.metacpan.org/source/JMCNAMARA/Excel-Writer-XLSX-0.98/examples/cgi.pl should work

It works. It will be downloaded. I can open it.

The code I hv given prints a NICE doughnut chart inside excel file. I ONLY need it to display via web browser. I don't need to download the whole excel file

When I use gd:graph, it can be done with below code

print "Content-type: image/png\n\n";
binmode STDOUT;
print $myimage->png;
[download]

How can I achieve it with Excel::Writer::XLSX ?
