Is there an easy way to remove all styling for an Excel export. Out of the box I get an export with a background color and no grid lines. Is there a way to prevent any style from passing to the Excel document?
This is the way Microsoft Excel interprets the HTML Excel content. If you open the output file in Notepad++ or similar, you will notice that we don't explicitly set background color or grid lines.
I recommend you switch to ExcelML format if this appearance is not suitable for your scenario.
