Hi Sutthipong,

Hi Sutthipong, 

Thanks for your patience. 

We are unable to reproduce the reported exception while opening the shared Excel document in Ubuntu. We have checked the issue in Ubuntu version 16.4

We request you to share the Ubuntu Version and Syncfusion XlsIO version you are using at your end, which will be helpful for us to investigate further and provide prompt solution at the earliest.

Mine using Syncfusion XlsIo.Net.Core
Server is Ubuntu 18.04

Hi Sutthipong, 

Thank you for updating us. 

We are unable to reproduce the reported issue. However, we have fixed the issue based on the shared stack trace. The patch to resolve issue can be downloaded from the following link. 

Recommended approach - exe will perform automatic configuration         
Please find the patch setup from below location:         
Advanced approach – use only if you have specific needs and can directly replace existing assemblies for your build environment         
Please find the patch assemblies alone from below location:         
Assembly Version:         
Installation Directions :          
This patch should replace the files “Syncfusion.XlsIO.Portable.dll” under the following folder.         
$system drive:\ Files\Syncfusion\Essential Studio\$Version # \precompiledassemblies\$Version#\4.6         
Eg : $system drive:\Program Files\Syncfusion\Essential Studio\\precompiledassemblies\\4.6      
To automatically run the Assembly Manager, please check the Run assembly manager checkbox option while installing the patch. If this option is unchecked, the patch will replace the assemblies in precompiled assemblies’ folder only. Then, you will have to manually copy and paste them to the preferred location or you will have to run the Syncfusion Assembly Manager application (available from the Syncfusion Dashboard, installed as a shortcut in the Application menu) to re-install assemblies.         
Note :          
You can change how you receive bug fixes by navigating to the following link and updating your preferences.          
Disclaimer :          
If you have received other patches for the same version for other products, please apply all patches in the order received.         
This fix will be included in our release version 17.4-SP1 which will be rolled out by end of January 2020.      

Kindly try and let us know if the issue is resolved at your end.
