Hi @andriy.andrukhovski I use MS word to open the docx file, which was converted from Pdf by AsposePdf, and save it to XML, there is no broken format, so the issue is not with Aspose.Pdf but with the Aspose.Word itself. Can you help to pass this to the dev team or should I create another topic for Aspose.Word? I attached all files here so it is easier for you to compare.

@JamesNguyen Unfortunately, I cannot reproduce the exact problem on my side using the latest 24.2 version of Aspose.Words. Here is XML document produced on my side using the following simple code:
Document doc = new Document(@"C:\Temp\in.docx");
doc.Save(@"C:\temp\out.xml", SaveFormat.FlatOpc);

Though I see problem with table borders, which are lost after conversion.

Thanks for your quick reply @alexey.noskov , for more information I used version 23.10, and was able to see the format improved after upgrading to 24.2 like you mentioned. But same like what you said, still issue with the table border, looking forward to when it will be fixed
