Export Forum locally

[Soldf]

I would like to export a specfic sub-forum of our Invision community to keep locally. 

Is there a way to export it in a readable format?
Like local HTML. 

I've tried to use some Site-crawlers but it has not worked to limit it to a specific forum.

There is no way in which to export a full forum in that manner. The only way in which to keep it locally would be to create a full copy of your site
