using Syncfusion.XlsIORenderer; 

Step 4: Include the following code snippet to convert Excel sheets to images and save them as a GIF.
C#

using (ExcelEngine excelEngine = new ExcelEngine())
{
   IApplication application = excelEngine.Excel;
   application.DefaultVersion = ExcelVersion.Xlsx;
   
   //Load an input template
   using(FileStream file = new FileStream("../../../Data/InputTemplate.xlsx", FileMode.Open, FileAccess.Read))
   {
       IWorkbook workbook = application.Workbooks.Open(file);

       using (MagickImageCollection collection = new MagickImageCollection())
       {
           for (int i = 0; i < workbook.Worksheets.Count; i++)
           {
               IWorksheet worksheet = workbook.Worksheets[i];

               //Initialize XlsIORenderer
               application.XlsIORenderer = new XlsIORenderer();

               //Create a memory stream to save the image
               using (MemoryStream stream = new MemoryStream())
               {
                   //Convert worksheet to image and save it to stream
                   worksheet.ConvertToImage(1, 1, 27, 12, stream);

                   //Set stream postition
                   stream.Position = 0;

                   //Load the image into MagickImage
                   MagickImage image = new MagickImage(stream);

                   //Add the image to the collection
                   collection.Add(image);
               }
           }

           //Set the delay between frames (100 = 1 second)
           foreach (MagickImage image in collection)
           {
               image.AnimationDelay = 100;
           }

           //Create an animated GIF
           collection.Write(@"..\..\..\Output\animated.gif");
       }
   }
}
