Workbook CalculateFormula very slow


I have been trying to use the Workbook.CalculateFormula() method to refresh the formulas on a spreadsheet but this seems to be very slow when dealing with a large number of formulas.

I have atatched an example spreadsheet showing the tyep of daat I am working with. My test code just looks like:

string templatePath = @"C:\TEMP\GRG_ALLCompsNov.xlsx";

string fileName = @"C:\TEMP2\GRG_ALLCompsNov.xlsx";

Aspose.Cells.Workbook myWorkbook = new Workbook();



myWorkbook.Save(fileName, Aspose.Cells.FileFormatType.Excel2007Xlsx);

If I remove the step to calculate formulas then this takes a few seconds - with the step included this does not complete even after 5 minutes.

Can you advise what I can do about this?

Many Thanks


Thanks for the sample file.

I can notice the issue as you have mentioned. I tried the following code with v7.3.5.3 (latest version/fix) using the template file, it takes more time than it should.

Sample code:

string templatePath = @"e:\test2\GRG_ALLCompsNov.xlsx";

string fileName = @"e:\test2\outGRG_ALLCompsNov.xlsx";

Aspose.Cells.Workbook myWorkbook = new Workbook(templatePath);
//This also does not make any difference.
//myWorkbook.Settings.CreateCalcChain = false;
