C#

using (ExcelEngine excelEngine = new ExcelEngine())
{
    IApplication application = excelEngine.Excel;
    application.DefaultVersion = ExcelVersion.Xlsx;
    FileStream inputStream = new FileStream(Path.GetFullPath(@"Data/InputTemplate.xlsx"), FileMode.Open, FileAccess.Read);
    IWorkbook workbook = application.Workbooks.Open(inputStream);
    IWorksheet worksheet = workbook.Worksheets[0];
    IWorksheet pivotSheet = workbook.Worksheets[1];

    //Create Pivot cache with the given data range
    IPivotCache cache = workbook.PivotCaches.Add(worksheet["A1:C9"]);

    //Create PivotTable with the cache at the specified location
    IPivotTable pivotTable = pivotSheet.PivotTables.Add("PivotTable1", pivotSheet["A1"], cache);

    //Add Pivot table field
    IPivotField regionField = pivotTable.Fields["Region"];
    regionField.Axis = PivotAxisTypes.Row;

    //Hide subtotals
    regionField.Subtotals = PivotSubtotalTypes.None;

    //Add Pivot table field
    IPivotField categoryField = pivotTable.Fields["Category"];
    categoryField.Axis = PivotAxisTypes.Row;

    //Hide subtotals
    categoryField.Subtotals = PivotSubtotalTypes.None;

    //Add data field
    IPivotField dataField = pivotTable.Fields["Sales"];
    pivotTable.DataFields.Add(dataField, "Total Sales", PivotSubtotalTypes.Sum);

    #region Save
    //Saving the workbook
    FileStream outputStream = new FileStream(Path.GetFullPath("Output.xlsx"), FileMode.Create, FileAccess.Write);
    workbook.SaveAs(outputStream);
    #endregion

    //Dispose streams
    outputStream.Dispose();
    inputStream.Dispose();
}

VB.NET

Using excelEngine As New ExcelEngine()
    Dim application As IApplication = excelEngine.Excel
    application.DefaultVersion = ExcelVersion.Xlsx
    Dim workbook As IWorkbook = application.Workbooks.Open("InputTemplate.xlsx")
    Dim worksheet As IWorksheet = workbook.Worksheets(0)
    Dim pivotSheet As IWorksheet = workbook.Worksheets(1)

    'Create Pivot cache with the given data range
    Dim cache As IPivotCache = workbook.PivotCaches.Add(worksheet("A1:C9"))

    'Create PivotTable with the cache at the specified location
    Dim pivotTable As IPivotTable = pivotSheet.PivotTables.Add("PivotTable1", pivotSheet("A1"), cache)

    'Add Pivot table field
    Dim regionField As IPivotField = pivotTable.Fields("Region")
    regionField.Axis = PivotAxisTypes.Row

    'Hide subtotals
    regionField.Subtotals = PivotSubtotalTypes.None

    'Add Pivot table field
    Dim categoryField As IPivotField = pivotTable.Fields("Category")
    categoryField.Axis = PivotAxisTypes.Row

    'Hide subtotals
    categoryField.Subtotals = PivotSubtotalTypes.None

    'Add Data Field
    Dim salesField As IPivotField = pivotTable.Fields("Sales")
    pivotTable.DataFields.Add(salesField, "Total Sales", PivotSubtotalTypes.Sum)

    'Saving the workbook
