How to update fill word(docx) template document.

Hi,

I need to fill an existing word (.docx) document which has some content control fields already.

The requirement is, that the user should fill some data in K2 form the click a button. The action for that button is to populate the entered data to an existing word document, each single text field should be filled in a specific content control in that .docx file.

Is it possible ? .. How it can be achieved please ?

Note: I have an experience in dot.net, if that can help in achieving this.

Thanks in advance!
