How to maintain leading zeros in WinForms XlsIO Excel cell
Leading zeros will be omitted from the value in an Excel cell, and this is the behavior of Microsoft Excel. There are two ways to maintain leading zeros in an Excel cell. They are:
1. Set the number format as “Text” and then assign the number with leading zeros using the Value property.
C#
worksheet.Range["A1"].NumberFormat = "@"; worksheet.Range["A1"].Value = "0123456789";
VB.NET
worksheet.Range("A1").NumberFormat = "@"
worksheet.Range("A1").Value = "0123456789"
2. Set the number format as “0000000000” and then assign the number with leading zeros using the SetValueRowCol method.
C#
worksheet.Range["A2"].NumberFormat = "0000000000";
worksheet.SetValueRowCol("0123456789", 2, 1);
VB.NET
worksheet.Range("A2").NumberFormat = "0000000000"
worksheet.SetValueRowCol("0123456789", 2, 1)
The following complete code snippet explains both the above scenarios.
C#
using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2016;
IWorkbook workbook = application.Workbooks.Create(1);
IWorksheet worksheet = workbook.Worksheets[0];
// Increasing column width
worksheet.Range["A1"].ColumnWidth = 15;
// Assign the number format as "Text" and then set a number with leading zeros using the Value property
worksheet.Range["A1"].NumberFormat = "@";
worksheet.Range["A1"].Value = "0123456789";
// Assign the number format and then set a number with leading zeros using the SetValueRowCol method
worksheet.Range["A2"].NumberFormat = "0000000000";
worksheet.SetValueRowCol("0123456789", 2, 1);
workbook.SaveAs("Output.xlsx");
System.Diagnostics.Process.Start("Output.xlsx");
}
VB.NET
Using excelEngine As ExcelEngine = New ExcelEngine
Dim application As IApplication = excelEngine.Excel
application.DefaultVersion = ExcelVersion.Excel2016
Dim workbook As IWorkbook = application.Workbooks.Create(1)
Dim worksheet As IWorksheet = workbook.Worksheets(0)
' Increasing column width
worksheet.Range("A1").ColumnWidth = 15
' Assign the number format as "Text" and then set a number with leading zeros using the Value property
worksheet.Range("A1").NumberFormat = "@"
worksheet.Range("A1").Value = "0123456789"
' Assign the number format and then set a number with leading zeros using the SetValueRowCol method
worksheet.Range("A2").NumberFormat = "0000000000"
worksheet.SetValueRowCol("0123456789", 2, 1)
workbook.SaveAs("Output.xlsx")
System.Diagnostics.Process.Start("Output.xlsx")
