Aspose may have incorrect implementation/interpretation to open incorrect file format

Hi James,


I downloaded and used your provided Excel file with Aspose.Cells V 7.2.0.6, and found that the workbook was loaded without any problem. For further investigation, I manually checked the debug data for the objects/shapes contained in the workbook, and could not find any problem with these as well. Also, MS-Excel is able to open it without any problems.

Can you please tell us about the error message given by the other third party library, so that we can have a better idea of the problem’s nature. Also, if you could tell us which other library you are using, it may be helpful for us.

Thanks

Hi Kashif,

SpreadsheetGear is the third party library.

It throws, "Corrupt OpenXML document." as error message.

We greatly appreciate your co-operation in this.

Cheers, Bhavin

Thank you Bhavin for the information. This will indeed help us in the diagnosis.


I would like to have one more piece of information. Have you generated the attached excel file using Aspose.Cells or MS-Excel?

Thanks & Best Regards,

Hi Kashif,

The attached file was originally created by MS-Excel.

Then it was modified by SpreadsheetGear twice and saved twice.

Hi,

You need to set OoxmlSaveOptions.ExportCellName property.

Please see the following code.

C#


Workbook workbook = new Workbook();

OoxmlSaveOptions saveOptions = new OoxmlSaveOptions();

saveOptions.ExportCellName = true;

workbook.Save(@“D:\FileTemp\dest.xlsx”,saveOptions);

10

Hi Shakeel,

I have tried the suggestion you mentioned; Setting OoxmlSaveOptions.ExportCellName property to true.

But, SpreadsheetGear still throws exception while opening file "Corrupt open xml document".

I really appreciate the help and support here.

Thanks heaps,

Bhavin.

Hi,

Thank you.

Could you please download and try the latest version:
Aspose.Cells
for .NET v7.2.0.8
with the same code as shown below and let me know your findings.

Please also post screenshots showing error in a SpreadsheetGear, it will help us sort out this issue quickly.

C#


Workbook workbook = new Workbook();

OoxmlSaveOptions saveOptions = new OoxmlSaveOptions();

saveOptions.ExportCellName = true;

workbook.Save(@“D:\FileTemp\dest.xlsx”,saveOptions);

Hi Shakeel,

Thank you for the reply,

Unfortuneatly, the latest DLL version 7.2.0.8 does not resolve the issue.

Please find attached screenshot of the exception/error detail in SpreadsheetGear.

Cheers, Bhavin

Hi,

Hi,

If a namespace is re-defined in the child node (<a:solidFill
xmlns:a=http://schemas.openxmlformats.org/drawingml/2006/main">),
SpreadGear could not parse the file. Maybe it’s the bug of
SpreadGear.

Anyways we will remove the duplicate defined namespace if it’s
not needed.

15

Hi,

We have fixed this issue.

Please download and try the latest fix: Aspose.Cells for .NET v7.2.1.1

16

Hi Shakeel,

Unfortuneatly, SpreadsheetGear still fails with the same error/exception from my previous post.

Is there anything other than duplicate namespace removal required from the open xml format??

Please investigate further,

Regards,

Bhavin
