@Glority_Developer,

I guess you are using Aspose.Words API and not Aspose.Cells API since you are converting your MS Word document (as per your attachment) to PDF file format. Correct me if I am wrong?

After your confirmation, I will move your thread to Aspose.Words forum where you will be assisted accordingly.

Yeah you are correct, I am so sorry for that, please help me move my thread to Aspose.Words forum, Thanks!

@Glority_Developer,

After an initial test with the licensed latest (20.10) version of Aspose.Words for .NET, we were unable to reproduce this issue on our end. We used the following simple code to test “111MB.doc” file to PDF format conversion on our end:

Document doc = new Document("C:\\temp\\111MB.doc");
doc.Save("C:\\temp\\20.10.pdf");

We suggest you to please upgrade to the latest version of Aspose.Words. In case the problem still remains, then please provide the exact code snippet that we can use on our end to reproduce the same exception.
