Aspose.Cells 7.5.1 throws Index out of range exception for .xltx file created by Excel 2013

I have encountered an exception when trying to save an .xltx file that was created/last saved using Excel 2013. The exception appears to be inconsistent as other .xltx files created using the same process are saved without throwing an exception.


I am using Aspose.Cells version 7.5.1 as this version resolved a “hanging” problem while attempting to open 2013-created files.

I am receive the exception “Index was out of range. Must be non-negative and less than the size of the collection.\r\nParameter name: index” when calling the Workbook.Save method.

I have included attached the file in question in hopes of expediting a solution.

Hi,


Thanks for providing us your template Excel file.

After an initial test, I observed the issue as you mentioned. I got the similar exception when re-saving the template XLTX file you provided. I used the following sample code:

Sample code:
Workbook workbook = new Workbook(“e:\test2\Account-Summary.xltx”);
workbook.Save(“e:\test2\out1.xlsx”, SaveFormat.Xltx);

I have logged a ticket with an id “CELLSNET-41873” for your issue. We will look into your issue soon.

Once we have any update on it, we will let you know here.

Thank you.
