We use Aspose.Cells to deal with lots of formattings, and we found it does not support custom format very well. Here is a bug we recently discovered.
In Excel, I have 2 cells valued 6,113 and -6,113, with custom format "#,##0.0,;(#,##0.0,)". Excel shows correctly result: 6.1 and (6.1). But when I open Excel file with Aspose, I got stringvalue as 6.1 and (6,113). I think Aspose cannot handle format on negative numbers.
I wonder if I can get a fix ASAP since it is an urgent client issue. Besides, I'd like to get both .Net 1.1 and 2.0 versions since our application supports both.
