Workbook workbook = new Workbook();
//Load an Excel sample document
workbook.LoadFromFile(@"sample.xlsx");
//Get the first worksheet
Worksheet sheet = workbook.Worksheets[0];
//Save the worksheet as an image

}
}
}
Convert a Specific Cell Range to an Image
In addition to converting a whole worksheet to an image, Spire.XLS for .NET also supports converting a specific cell range of a worksheet to an image. Detailed steps are listed below.

using Spire.Xls;
using System.Drawing.Imaging;
namespace SpecificCellsToImage

static void Main(string[] args)
{
//Create a Workbook instance
Workbook workbook = new Workbook();
//Load an Excel sample document
workbook.LoadFromFile(@"sample.xlsx");
//Get the first worksheet
Worksheet sheet = workbook.Worksheets[0];
//Specify a cell range and save it to a certain image format
