Hello @ashar02 ,

For this, you need to use Multipart/form-data. POST form data into the servlet and you can receive the image from the body part.

Once you got the image convert it into inputStream and put it into the excel cell.

The Java servlet code will be like this

RequestParameterMap requestParameterMap = request.getRequestParameterMap(); RequestParameter image = requestParameterMap.getValue("image"); InputStream inputStream = image.getInputStream();
