I have a requirement where end user will upload a document in one of the task an

I don't know of any OOB functionality that would do this, outside of manually pulling the contents from the docx (zip) file and undergoing the incredibly complex process of manually parsing the document.xml file (which defines the basic word document, including formatting, tables, etc). I would suggest searching around various plug-ins to see if there's anything that comes close.

I think the short answer is "No". What is the reason for uploading the document? Is there another format you can use? Maybe the data and images could be entered in a screen rather than the word document?

Not an elegant solution, but a while back on a project, when a document was uploaded we used a custom plugin to loop through the pages of the document and convert them to images. Then each page was an image that we could show on the record dashboard. Not elegant, high in CPU usage, custom plugin.
So, I guess what I am saying is it is possible, but not advised.
What is the use case reasoning? could there maybe be an alternate solution?

Hi Christineh. That is exactly what I want to implement. Can you tell me the plugin name?
