I have a Microsoft Word Document (docx) and I use Open XML SDK 2.0 Productivity Tool to generate C# code from it.
I want to programmatically insert some database values
For those looking for manual non-programmatic solution:

I've tested that free-trial of memoQ 2014 can indeed be used as a bulky workaround for cleaning Word spell tags.
Still looking for an easier ready-out-of-the-box tool.
