Creating Pivot Table c# interop

I am trying to create a Pivot Table from a full Worksheet with C# interop but I am getting some errors, don't know if is my code or this example is old.
I am following this example: Creating a Pivot Table c#
But when I try it, I can't find some methods.
This is my code:
Microsoft.Office.Interop.Excel.Application Excel = new Microsoft.Office.Interop.Excel.Application();
Workbooks libro = Excel.Workbooks;
Workbook libroActual = libro.Add();
Sheets sheets = libroActual.Worksheets;
//Excel.Workbooks.Add();
// Instanciamos la hora activa
Microsoft.Office.Interop.Excel._Worksheet Worksheet = Excel.ActiveSheet;
Worksheet.Name = "Desglose";
Worksheet sheetMMPP = Excel.Worksheets.Add();
sheetMMPP.Name = "MMPP";// CreateEmptySheet();
Microsoft.Office.Interop.Excel.Range dataRange = Worksheet.UsedRange;
Microsoft.Office.Interop.Excel.PivotCache cache = (Microsoft.Office.Interop.Excel.PivotCache)libroActual.PivotCaches().Add(Microsoft.Office.Interop.Excel.XlPivotTableSourceType.xlDatabase,dataRange);
Microsoft.Office.Interop.Excel.PivotTable pt = (Microsoft.Office.Interop.Excel.PivotTable)sheetMMPP.PivotTables().Add("Pivot Table", Worksheet.Range["A1"], cache);
Microsoft.Office.Interop.Excel.PivotField oPivotField = (Microsoft.Office.Interop.Excel.PivotField)pt.PivotFields("Nivel 0");
oPivotField.Orientation = Microsoft.Office.Interop.Excel.XlPivotFieldOrientation.xlDataField;
oPivotField.Function = Microsoft.Office.Interop.Excel.XlConsolidationFunction.xlSum;
oPivotField.Name = "Nivel 0";
But I get this error:
Could not convert argument 2 for call to Add
The error is in this line:
Microsoft.Office.Interop.Excel.PivotTable pt = (Microsoft.Office.Interop.Excel.PivotTable)sheetMMPP.PivotTables().Add("Pivot Table", Worksheet.Range["A1", "P56"], cache);
Someone knows about this error?

Looks like you've mixed up libraries. In your link, the example is based on the Spire.xls library, but in the code you use Interop.Excel with Spire syntax. The Interop.Excel PivotTables.Add method has different parameters - Add (Microsoft.Office.Interop.Excel.PivotCache PivotCache, object TableDestination, [object TableName], [object ReadData], [object DefaultVersion])

Append data to excel sheet if created using ClosedXML in c#

I am writing an application in which I need to store data cell values into excel sheet. Everything is working fine but the problem is everytime I run the application, it overwrites the existing data.
So far the code I have taken from Github:
var workbook = new XLWorkbook();
var worksheet = workbook.Worksheets.Add("Sample Sheet");
worksheet.Cell("A1").Value = this.textBox1.Text;
worksheet.Cell("B1").Value = this.textBox2.Text;
worksheet.Cell("C1").Value = this.textBox3.Text;
worksheet.Cell("D1").Value = col1;
worksheet.Cell("E1").Value = col2;
worksheet.Cell("F1").Value = this.textBox6.Text;
workbook.SaveAs("HelloWorld.xlsx");
Note: I don't want to save data using datatable or anything. I just want to get values from textboxes and append them to the existing sheet. I have visited many stackoverflow post but they doesn't helped me much.
Thanks in advance!

Hope this helps:
var wb = new XLWorkbook("Path to file");
IXLWorksheet Worksheet = wb.Worksheet("Tab name");
int NumberOfLastRow = Worksheet.LastRowUsed().RowNumber();
IXLCell CellForNewData = Worksheet.Cell(NumberOfLastRow + 1, 1);
CellForNewData.InsertData(your_data);

You are explicitly storing the values in row 1 of the spreadsheet. If you want to append the values, you'll have to increment the row number and store the values in the appropriate cells.

How to add a new excel column between two columns in a existing worksheet

I would like to add a column that already contains cells values between two columns (or at the end) of a worksheet of an existing workbook that I load.
So I have a function that sets that "column values" I need :
private static Workbook SetIndicatorsWorkbook()
{
var workbook = new Workbook(WorkbookFormat.Excel2007MacroEnabled);
var worksheet = workbook.Worksheets.Add("Unit & Integration Tests");
//Don't worry about team and jenkinsBuilTeams variables
foreach (var team in jenkinsBuildTeams)
{
worksheet.Rows[posX].Cells[0].Value = lastnbUnitTests + lastnbIntegrationTests;
posX += 1;
}
return workbook;
}
And then in main function I want to add this column (which is workbook.worksheets[0].Columns[0] ) in a loaded workbook :
private static void Main()
{
//The workbook I need to update
Workbook workbook = Workbook.Load("file.xlsx");
Workbook temp = SetIndicatorsWorkbook();
WorksheetColumn wc = temp.Worksheets[0].Columns[0];
//The issue is that Worksheet's Columns collection has no "Insert" property
workbook.Save("file.xlsx");
}

The Columns collection of the Worksheet has an Insert method that will shift data/formatting just as would happen in Excel. This was added in the 2014 volume 2 version. You can read more about that in the help topic or the api documentation. Note I've linked to the WPF version help but the Insert method is available in the other platforms as well.

Open XML move sheets in workbook

Using OpenXml on a excel sheet i create new worksheet.
newWorksheetPart.Worksheet = new Worksheet(new SheetData());
Sheet sheet = new Sheet()
{ Id = relationshipId, SheetId = sheetId, Name = sheetName };
workBookSheets.Append(sheet);
How do i move this newly created worksheet in the place of a another worksheet ?
For example :There are three worksheets
A,B,C and i create a new worksheet A1 and want A1 to be in the place of B . How do i go about this ?
Thanks

I believe you can do something like this:
document.WorkbookPart.Workbook.Sheets.InsertBefore(sheet, sheetB);
Where "sheetB" would be the OpenXMLElement. So rather than appending the sheet to the workbook you would insert sheet A1 before sheet B.
I was able to make a sheet the first in the workbook by doing the following:
document.WorkbookPart.Workbook.Sheets.InsertBefore(sheet,
document.WorkbookPart.Workbook.Sheets.FirstChild);

How to copy one worksheet to another worksheet on within workbook using aspose.cell

How can i copy one worksheet values and paste an another worksheet on within a workbook in aspose.cell using asp.net with c#?
Thanks and regard,

I work as Social Media developer at Aspose. Aspose.Cells offer multiple options to achieve your desired results. You can Export the data from one worksheet to another and then import the data to the destination worksheet using . You can also copy all the data as range to the destination worksheet. Check the following samples:
Copy the Range from First Worksheet to destination worksheet
//Open the workbook
Workbook workbook = new Workbook("book1.xlsx");
//Select source worksheet
Worksheet worksheet = workbook.Worksheets[0];
//Select Destination Worksheet
Worksheet destSheet = workbook.Worksheets[1];
//Get the range of cells with all the data from source worksheet
Aspose.Cells.Range sourceRange = worksheet.Cells.MaxDisplayRange;
//Create a range with same row and column count as source worksheet
Aspose.Cells.Range destRange = destSheet.Cells.CreateRange(sourceRange.FirstRow, sourceRange.FirstColumn, sourceRange.RowCount, sourceRange.ColumnCount);
//Select Paste Options
PasteOptions options = new PasteOptions();
options.PasteType = PasteType.All;
//Copy the range from source worksheet to destination.
destRange.Copy(sourceRange, options);
//Save the updated worksheet
workbook.Save("book1.xlsx");
Export data from one worksheet and import to another
//Open the workbook
Workbook workbook = new Workbook("book1.xlsx");
//Select source worksheet
Worksheet worksheet = workbook.Worksheets[0];
//Exporting the of worksheet to DataTable
DataTable dataTable = worksheet.Cells.ExportDataTableAsString(0, 0, worksheet.Cells.MaxRow, worksheet.Cells.MaxColumn, true);
//Select Destination Worksheet
Worksheet destSheet = workbook.Worksheets[1];
//Import data to destination worksheet
destSheet.Cells.ImportDataTable(dataTable, true, "A1");
//Save the updated worksheet
workbook.Save("book1.xlsx");
