Convert Pdf to Docx via API losing format

Hi everyone,

I am trying to convert Pdf to Docx via Adobe services API, I followed the sample here https://developer.adobe.com/document-services/docs/overview/pdf-services-api/howtos/export-pdf/. After getting output, it look fine as first, but when I check it in XML format, almost everyword become its own element, so it doesn't maintain the original sentence, paragraph anymore. Is there any option to keep the elements together as it should be?

Regards,

James Nguyen
