When I open an excel file by Aspose (file attach), I saw that the Double Value & String Value in the cell (C3) were not correct:
DoubleValue = -1223.0, StringValue = -$-1409
if it is correct, the values will be:
DoubleValue = -1223.0, StringValue = -$ 1.223,00
Thanks for pointing it out.
We will figure out your issue soon.
