Hi Justin,
I tried with the following codes. It works fine. Could you post your template file and sample codes? We will check it soon.
//Instantiating an Workbook object
Workbook workbook = new Workbook();
//Obtaining the reference of the newly added worksheet
Worksheet sheet = workbook.Worksheets[0];
Cells cells = sheet.Cells;
//Setting the value to the cells
Aspose.Cells.Cell cell = cells["A1"];
cell.PutValue("Sport");
cell = cells["B1"];
cell.PutValue("Quarter test");
cell = cells["C1"];
cell.PutValue("Sales");
cell = cells["D1"];
cell.PutValue("Sales1");
cell = cells["A2"];
cell.PutValue("Golf");
cell = cells["A3"];
cell.PutValue("Golf");
cell = cells["A4"];
cell.PutValue("Tennis");
cell = cells["A5"];
cell.PutValue("Tennis");
cell = cells["A6"];
cell.PutValue("Tennis");
cell = cells["A7"];
cell.PutValue("Tennis");
cell = cells["A8"];
cell.PutValue("Golf");
cell = cells["B2"];
cell.PutValue("Qtr3");
cell = cells["B3"];
cell.PutValue("Qtr4");
cell = cells["B4"];
cell.PutValue("Qtr3");
cell = cells["B5"];
cell.PutValue("Qtr4");
cell = cells["B6"];
cell.PutValue("Qtr3");
cell = cells["B7"];
cell.PutValue("Qtr4");
cell = cells["B8"];
cell.PutValue("Qtr3");
cell = cells["C2"];
cell.PutValue(1500);
cell = cells["C3"];
cell.PutValue(2000);
cell = cells["C4"];
cell.PutValue(600);
cell = cells["C5"];
cell.PutValue(1500);
cell = cells["C6"];
cell.PutValue(4070);
cell = cells["C7"];
cell.PutValue(5000);
cell = cells["C8"];
cell.PutValue(6430);
cell = cells["D2"];
cell.PutValue(0);
cell = cells["D3"];
cell.PutValue(0);
cell = cells["D4"];
cell.PutValue(0);
cell = cells["D5"];
cell.PutValue(0);
cell = cells["D6"];
cell.PutValue(0);
cell = cells["D7"];
cell.PutValue(0);
cell = cells["D8"];
cell.PutValue(0);
PivotTables pivotTables = sheet.PivotTables;
//Adding a PivotTable to the worksheet
int index = pivotTables.Add("=Sheet1!A1:D8", "E20", "PivotTable1");
//Accessing the instance of the newly added PivotTable
PivotTable pivotTable = pivotTables[index];
//Unshowing grand totals for rows.
// pivotTable.RowGrand = false;
//Draging the first field to the row area.
pivotTable.AddFieldToArea(PivotFieldType.Row, 0);
//Draging the second field to the column area.
pivotTable.AddFieldToArea(PivotFieldType.Column, 1);
pivotTable.AddCalculatedField("test", "=IF(ISERROR(Sales/Sales1),0,5)");
//// pivotTable.AutoFormatType = PivotTableAutoFormatType.Table1;
//pivotTable.AddFieldToArea(PivotFieldType.Data, 2);
//pivotTable.DataFields[0].NumberFormat = "yyyy-mm-dd";
//pivotTable.RowFields[1].HideDetail(true);
workbook.Save(@"F:\FileTemp\dest.xls");
