CellsException in CalculateFormula() using the Excel Function TREND()


I tried to find out what happens if I calculate an unsupported excel function.

The function “=TREND(A2:A10)” is successfully calculated in Excel, but the CalculateFormula() method throws a CellsException:

"Index was out of range. Must be non-negative and less than the size of the collection.\r\nParameter name: index\nError in calculating cell A1 in Worksheet Sheet1"

Wouldn’t it be better if the CalculateFormula() method would skip such cells?

Btw. Is the List of Supported Functions still up to date? It wasn’t easy to find a fully unsupported function. For example all Date and Time Functions were calculated correctly.

I’m currently using version

Thanks in advance!


See the document:
The page denotes those functions which are not supported. The functions that are not listed in the page should be considered as supported by the formula calculation engine of Aspose.Cells for .NET.

TREND() should work fine with CalculateFormula() method. Could you try our latest fix v7.1.1.5: Aspose.Cells for .NET v7.1.1.5
If you still find any issue, kindly give a sample template file to reproduce the issue on our end, we will check your issue soon.

Also to skip the unsupported function, please use:
Workbook.CalculateFormula(true) for your needs.

Thank you.
