Hi, thanks for the solution.
It did help to set the background color for the .header-center class.
But for the ".header-top", I tried to do the same but strangely, it did not work for the color black / #000000.
It did work for other colors though...
Any idea why is this happening?

I'm having trouble getting the background color to display in excel.

As mentioned in title, the chrome-pdf works but the html-to-xlsx doesn't.

Here is the playground: https://playground.jsreport.net/w/anon/QK7qB5AE

On a side note, not sure why in the above sample playground the excel generation takes quite a reasonable time to generate the excel but in my local jsreport, it is taking me at least 10s to generate the above same excel.

Thanks for the help in advanced!
