Hi Peter,

Please send your file and sample code to nanjing@aspose.com.
By the way, which version of Aspose.Cells are you using?


Thank you for the sample code. Could you please also send me the template file? Thank you very much.


I have found the problem. Aspose can’t find out to open a template with a workbook protectioncode when you not have the code to unprotect the excel template. when i remove the protection it worked.
