Problems with aspose.cells formula calculation

I’m using aspose.cells in an asp.net application. Before this I was using the interop methods and had no problems. The problem is that some formulas are not being correctly calculated with some specific inputs. For checking I’ve made a save of the .xls and compared with my original .xls and everything is in order. I can’t send the original .xls for privacy reasons but bellow is the code I’m using to access the .xls.

return instancia;

Please HELP!!!

Hi,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Thank you for considering Aspose.

From your provided code it is not clear to us that which formulas are actually causing the problem.

Thank You & Best Regards,

Thanks for the rapid response.
I’ll check if I can send you the Excel file and code.

Meanwhile I’ll try to explain the problem with more detail.
The problem appeared after doing the following in this order:
- “getInstancia” if first called
- “conectar”
- The “setDatosIngresados” method is called to Export the data to the Excel
(after this is when I tried the “save” method)
- The “getCelda” method is called

This last call returns “#N/A”. For a couple of cells, not for all.

The Excel has a VERY complicated logic for calculating the results. For this it uses fix and variable (user input) values in 10 different worksheets. My guess is that the problem might by in the order aspose.cells is calculating the results and/or where I place the “calculateFormula” method.

Thanks.
Felipe

Hi,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Thanks for further details, but it seems like some formula calculation problem. Your provided code is only setting the values in the excel template file and all the formulas are already in your excel file. The calculate formula actually calculates the results of all the formulas. Now, the #N/A may be occurring due to some wrong formula, wrong parameters in formula or may be some formula which is not supported by Aspose.Cells. So, we will not be sure what the problem is, until we can either know the exact formulas which are not working or we can check your template excel file. Hopefully you understand my point.

Thank You & Best Regards,
