Hi dnnyobi,

Refer below link and implement in Windows Application.

Create and split word document into two columns in ASP.Net

If any issue revert back with details.

I succeeded in using spire.doc as described in the link but I do not want any third party plugin or dll. Is there no way I can split without using 3rd party files?

Thank you.

 Can't it split without using a third party plugin or dll. I do not want to use spire.doc it is very expensive. The free version I downloaded allows 500 words only. Thank you.

There is no othere free library available currently. I am searching for it.

Try using Office library.
