How to preserve long number while exporting in XlsIO?
This article explains how to preserve a long number while exporting using WinForms XlsIO.
A long number can be preserved as a string while exporting, by enabling the `range.IsStringsPreserved` property. Instead of using this property for every range, you can also enable `IWorksheet.IsStringsPreserved`, which preserves all the values in the worksheet as strings.
To know more about the `IsStringsPreserved` property, please refer to the documentation.
Code snippet to preserve a long number as a string while exporting
worksheet.IsStringsPreserved = true;
The following C#/VB complete code explains how to preserve a long number while exporting using XlsIO.
C#
using Syncfusion.XlsIO;
using System.Data;
using System.IO;
namespace Preserve_LongNumber
{
class Program
{
static void Main(string[] args)
{
using (ExcelEngine excelEngine = new ExcelEngine())
{
// Instantiate the Excel application object.
IApplication application = excelEngine.Excel;
// Creating a workbook.
IWorkbook workbook = application.Workbooks.Create(1);
// The first worksheet object in the worksheets collection is accessed.
IWorksheet worksheet = workbook.Worksheets[0];
// Preserving data while exporting
worksheet.IsStringsPreserved = true;
worksheet["A1"].Value = "123456789987654321";
worksheet["A2"].Value = "TESTXXXXTESTXXXX";
DataTable dt = worksheet.ExportDataTable(worksheet.UsedRange, ExcelExportDataTableOptions.None);
// Long number preserved in data table
var value1 = dt.Rows[0].ItemArray.GetValue(0);
var value2 = dt.Rows[1].ItemArray.GetValue(0);
// Saving the workbook
Stream stream = File.Create("Output.xlsx");
workbook.SaveAs(stream);
}
}
}
}
VB
Imports Syncfusion.XlsIO
