Hi Andrew,

Thanks for your inquiry. Could you please attach your input Word document (.docx file), you're getting this exception with, here for testing? I will investigate the issue on my side and provide you more information.

All good I've changed the code to, I've attached doc:

Dim Stream As New System.IO.MemoryStream(Text.ASCIIEncoding.Default.GetBytes(HTMLDocumentText))
Dim NewDoc As New Aspose.Words.Document()
Dim DocBuilder As New Aspose.Words.DocumentBuilder(NewDoc)

DocBuilder.InsertHtml(HTMLDocumentText)

NewDoc.Save(FileName, DocumentSaveFormat)

Hi Andrew,

Thanks for the additional information.

Perhaps, you're using an older version of Aspose.Words; as with Aspose.Words v11.3.0, I was unable to reproduce this exception during loading test.docx file into Aspose.Words DOM. I would suggest you please upgrade to the latest version of Aspose.Words i.e. v11.3.0 and let us know how it goes on your side.

I hope, this will help.

Best Regards,
