Hi,
Thanks for your posting and using Aspose.Cells.
We have looked into this issue and found your file is corrupt. Please see the error shown by MS-Excel 2010 while opening your excel file. If your file is corrupt then Aspose.Cells will throw exception automatically. So it is not a bug but normal and expected behavior of Aspose.Cells.
so the problem is the file probably created with numbers by apple: with this app there is no error.
it means all files created with numbers can’t have a good conversion with Aspose?
Hi,
Thanks for your posting and using Aspose.Cells.
By Apple, do you mean MAC operating system. Which software is able to open such files? Are all files created by your software system corrupt or only this file is corrupt? You can verify by creating such files and then loading it using Aspose.Cells. You can also provide us such files for our investigation.
yes we mean Mac OSX system. As said the name of Apple’s Software is Numbers. We cannot say if all of customer’s files or just one is applicable to this condition. We can open it with numbers without any problems.
Hi Valerio,
- Record about picture is not valid
- The font name in style.xml is too large therefore Excel cannot not open it correctly.
Thanks
your files is just fine in numbers, as the original one
How we (actually our customers that could have this problem) can fix the second problem? is there a “user friendly procedure”?
