Hi,
sample code with your template file. I found Workbook.CalculateFormula
takes long time to calculate formulas in the template file.
e.g
Sample code:
string filePath = @"e:\test2\a2aa2da498dc416ea4903d01fe09961c_639-VILLENOY.xlsm";
Workbook workbook = new Workbook(filePath);
workbook.Settings.CreateCalcChain = false;
workbook.CalculateFormula(false);
Hi,
Thanks for using Aspose.Cells.
This issue is caused by calculating too many complex SUMPRODUCT function.
For example, The formula of the cell “F525” in the worksheet " Prépa tres":=SUMPRODUCT(($A$4:$A$514=$A525)($C$4:$C$514=“TOTAL”)(F$4:F$514))
In the current calculating engine, we will calculate it with the following steps:
1, calculate ($A$4:$A$514=$A525) as array1
2, calculate ($C$4:$C$514=“TOTAL”) as array2
3, calculate (F$4:F$514) as array3
4, calculate array1 * array2 as array4
5, calculate array3 * array4 as array5.
6, calculate SUMPRODUCT with array5.
We have to loop for 511 * 6 times for this formula now.
We are re-building the calculate engine now, the steps will be changed as :
1, calculate (($A$4=$A525)($C$4:=“TOTAL”)(F$4))
2, loop 1 for 511 times to get array1
3. calculate SUMPRODUCT with array5.
We only need to loop for 511 * 2 times in the new engine.
But this new engine could not be available soon.
Now we only can improve performance little in the current calculate engine.
The template file is not accessible. We have implemented the new formula engine in past versions. You may try our latest version and fixes to see whether this issue has been fixed. If not, please provide us the template file again and we will make further investigation.
