XML maps to Excel

We can also add XML mapping to an Excel document using our .NET Excel Library. XML mapping enables us to define which parts of the XML data should be imported into Excel and which sections can be exported back as XML, offering complete control over your data transformation process.

To do so, please add the following code and run the app.

using Syncfusion.XlsIO;

namespace XmlMapToExcel
{
    class Program
    {
        public static void Main(string[] args)
        {
            using (ExcelEngine excelEngine = new ExcelEngine())
            {
                IApplication application = excelEngine.Excel;
                application.DefaultVersion = ExcelVersion.Xlsx;
                IWorkbook workbook = application.Workbooks.Create(1);
                IWorksheet worksheet = workbook.Worksheets[0];

                // Import XML data into the worksheet
                FileStream inputStream = new FileStream("../../../Data/XmlFile.xml", FileMode.Open, FileAccess.Read);

                // Import XML mapping to Excel
                workbook.XmlMaps.Add(inputStream);

                // Saving the workbook as a stream
                FileStream outputStream = new FileStream("../../../Output/XmlMapOutput.xlsx", FileMode.Create, FileAccess.ReadWrite);
                workbook.SaveAs(outputStream);

                // Dispose stream
                inputStream.Dispose();
                outputStream.Dispose();
            }
        }
    }
}

Refer to the following image.

The screenshot above shows that only the XML mapping is added to the Excel document. With XML maps, we can easily select and control the specific data to be imported or exported between the XML file and the Excel sheet.
