DHTMLX Export excel for Image column

Is there an option to export an image to an excel?
If this option is not present we would like to replace the image with a text. While exporting if the image is present it should be “1” and if it is not present it should be “0”. Could you please help us with a solution for this.

sorry for the delay in answerring.
Please, have a look at method rowPrint in file gridExcelWrapper.php.
You may add your section in switch operator:

case 'img':
    // print 0 or 1 here
