Excel can solve many circular references using an iterative solution (100 cycles, converging value) and the same can do SpreadSheetGear.
Laurence some times ago told me that in 2 weeks also Aspose.Cells would have had this feature.
Now I need to deliver a project in the next days and I need to know if Aspose.Cells can solve this issue or if I have to purchase SpreadSheetGear.
If I can go with your component, I'd need a temporary licence (without demo banners) for both Aspose.Cells and Aspose.Pdf.
