It might not do graphics or charts but I was still blown away by how good this really is:

May as well quote my comment from https://core.trac.wordpress.org/ticket/27160#comment:4

I've got nothing of value to add to this ticket except to say this is awesome.

Probably my first, last and only Word 2013 to WordPress posts.

* 'Table of Contents' anchors match and work perfectly eg
* Tables work perfectly with , , , , etc, even cells left blank are handled perfectly.
* Imported and converted PDF -> Word 2013 - WordPress post, all good
* Unordered Lists are fine, using
* Ordered lists, I had one that didn't work and an awesome on that did kicking off with
* 140 page Word 2013 Document ~28,000 words to WordPress, not a single invalid HTML element...
* 80 page PDF opened in Word 2013, copy and paste to WordPress post, all good
* 1,000 rows by 30 column CSV (~65k words) open in Excel 2013, copy and paste to WP post, no problem
* ~250 rows x 15 column Access 2013 to WP post, wow, still no problems

I started off small then threw anything I could at WordPress, apart from formatting errors where images were in the original document that don't become part of the WordPress post via copy and paste I could not fault a thing.

I'd never recommend people to write in Word, Excel, Access and then copy and paste to WordPress, but if someone told me they did I would say "Isn't it an awesome WYSIWYG experience"
