I got a different result for Docx converting to Odt when I use the latest version of Aspose.Words for .NET i.e. 19.7.
There are three objects in 01.docx file. (see [1.jpg] 01.jpg (45.6 KB))
When converted “01.docx” to ODT format (see [2.jpg] 02.jpg (73.3 KB)
Opening the 02.odt file by using LibreOffice 126.96.36.199), the objects are different.
The objects on .Odt file are different from the .docx file.
You can see the different in the picture [3.jpg] 03.jpg (129.3 KB) .
You can try the sample code. ConsoleApp1.zip (4.7 MB)
Please help. Thanks a lot.
