Exception when refreshing pivot table containing field with date grouping

Aspose.Cells Product Family

test excel file.zip (9.8 KB)

The attached excel file contains a pivot table with a date field that is grouped by year and month. This works fine in Excel, but causes an exception in code when attempting to refresh. This occurs with the latest 17.8 release of Aspose.Cells for .NET.

The exception that is being thrown is System.FormatException. It also says “Input string was not in a correct format”. I believe it may have to do with the PivotItems that get created for the field such as “>2017”

    Dim excel As New Aspose.Cells.Workbook("c:\temp\test.xlsx")
    Dim sheet As Aspose.Cells.Worksheet = excel.Worksheets(0)
    Dim pivot As Aspose.Cells.Pivot.PivotTable = sheet.PivotTables(0)

    pivot.RefreshData()         'this works
    pivot.CalculateData()       'this doesn't work
    sheet.RefreshPivotTables()  'this also doesn't work

Using the original test file I uploaded, the problem is resolved with Aspose.Cells for .NET 17.9. However, I am still seeing the issue with a different file which I have attached.

@chrism.peloton,

Thanks for providing us template file.

Thanks for your confirmation on your issue was fixed with v17.9.
However, the same issue can be reproduced using your newly attached file. I used the following sample code with your new template file:
e.g
Sample code:

Aspose.Cells.Workbook excel = new Aspose.Cells.Workbook("e:\\test2\\test.xltm");

            foreach (Worksheet sheet in excel.Worksheets)
            {
                foreach (PivotTable pt in sheet.PivotTables)
                {
                    pt.RefreshData();
                    pt.CalculateData();//error occurred for the first worksheet's pivot table.
                    sheet.RefreshPivotTables();
                }
            }

I have reopened your issue. Our concerned developer from product team will look into it soon.
