Hi All,

I am try to create a empty workbook with only one worksheet.

what i did is:

for (int i = 0; i < this._workBook.Worksheets.Count; i++)
{
this._workBook.Worksheets.Remove(i);
}


this._workSheet = this._workBook.Worksheets.Create("My Demo Worksheet");
this._workSheet.Activate();

when i save the file, why there will be two worksheets?

Thanks

Hi Shrimpy,

Thank you very much for your interest in Syncfusion products.

As you have reported in your last update the code snippet will result with two worksheets in the output file. Because the code will remove from the starting index 0, so when the 0th index is removed, sheet in the 1st index will be moved to the 0th index but the code will remove from the 1st index [But actually you are removing the 2nd index sheet ]. I hope the input workbook has 5 sheets the code will remove in the below way

0 1 2 3 4
0 1 2 3 [When i==0]
0 1 2 [When i==1]
0 1 [When i==2]
I have modified the code snippet and placed below, please try the below code snippet at your side and let me know if this helps you.

[C#]
// Instantiate the spreadsheet creation engine.
ExcelEngine excelEngine = new ExcelEngine();

// Instantiate the Excel application object.
IApplication application = excelEngine.Excel;

string file = @"..\..\Book1.xlsx";

//Open the workbook
IWorkbook workbook = application.Workbooks.Open(file, ExcelOpenType.Automatic);

//Delete worksheets from workbook
for (int i = workbook.Worksheets.Count - 1; i > 0; i--)
workbook.Worksheets.Remove(i);

//Save the workbook
workbook.SaveAs("SampleOutput_NoSheetIndex.xlsx");

Please let me know if you need any clarifications.

Thanks,
Lokesh
