Work with Excel WorkSheets

An IronXL.WorkBook represents and entire Excel (XLSX or XLS) file.

An IronXL.WorkSheet represents one page or tab within that file.

C#:

using IronXL;

//This is how we create new worksheet
WorkBook workBook = WorkBook.Load("test.xlsx");

//This is how we create new worksheet
var newSheet = workBook.CreateWorkSheet("new_sheet");
//You can perform any operations you want with the new sheet.
newSheet["B2"].Value = DateTime.Now;


// Work with an existing Worksheets 
WorkSheet oldSheet = workbook.GetWorkSheet("sheet1");
//...

// Work with the first Worksheet
WorkSheet firstSheet = workbook.DefaultWorkSheet;
//...


//Save in Excel format or export to many other file formats
workBook.SaveAs("test.xlsx");

VB:

Imports IronXL

'This is how we create new worksheet
Private workBook As WorkBook = WorkBook.Load("test.xlsx")

'This is how we create new worksheet
Private newSheet = workBook.CreateWorkSheet("new_sheet")
'You can perform any operations you want with the new sheet.
Private newSheet("B2").Value = DateTime.Now


' Work with an existing Worksheets 
Private oldSheet As WorkSheet = workbook.GetWorkSheet("sheet1")
