Excel Pdf Save Error

When we want to save the attached document as pdf using Aspose Cells 21.8, the server crashes. But we do not get this error in version 21.12. Thanks for the fix.
But the problem is that our customer wants to impose a penalty because of this issue. Can we assure our customer that this issue will not be repeated? Or how we can control such situations without locking the server.
The problem occurs in the save method and an error is not thrown.NCZ-SPE-00474.zip (2.3 MB)


We will try our level best that this issue/regression should not be repeated in upcoming versions. You know API/SDK development is not straight line which is complex on its own and we always face challenges when implementing the new features and other improvements.

Furthermore, as the API development is not a constant path, you cannot always make it 100% bug free all the time. We always try to enhance/improve the component with each release of the product to make it more robust and feature rich APIs.

Thanks for your understanding!


Our customer told us that he wanted to know what was wrong with the document. For this, I prepared a web application for Cells 21.8 version. It crashes during save. Can you tell us the problem in the document?

I could not download your web project but I downloaded your template Excel file. I played upon with your Excel file in simple desktop VS.NET WinForm application to convert to PDF using our latest version (Aspose Cells for .NET v22.1.x) and older version (Aspose Cells for .NET 21.8). I found latest version just works fine and there is no error or issue, the PDF file is generated fine. But when I used older version, it continues to take long time before I manually stop the process (after a few minutes). It seems like a bug in older version regarding rendering to PDF which is resolved in newer versions. Please note, with each new version of the APIs, we embed enhancements and other improvements plus fixes regarding Excel to PDF rendering (internal module). So, it is quite possible that such an issue (as yours) is resolved automatically in later versions. We recommend to try to use latest version for your needs.

PS. we will also check if we could share the root cause of issue (why the older version could not render the file to PDF) by evaluating your document in details.


There was an issue in Aspose.Cells v21.8 while rendering a shape(see screenshot, highlighted by blue renctangle: shape_highlighted_by_blue_rectangle.jpg (266.9 KB) in the source file, and caused the infinite loop.

Thank you for your information. Our customer said that there was an error in the file, although the direct error was not received. In the attached file they sent us, the details in the original file and the erroneous details that occurred after the aspose save were specified. We are waiting for your solutions.

Yes, the underlying shape (as highlighted by @Peyton.Xu in the screenshot) is not rendered properly even using the latest version although no exception or delay occurred. Do you want us to log a ticket for the issue, please confirm? After your confirmation, we will log a ticket and the fix might be included in our upcoming release Aspose Cells for .NET v22.2.
