This module implements extra filtering of text pasted from Word. Yes, we have the awesome Pastefromword CKEditor plugin now in the Drupal core. But the pasted text is not perfect. It still has too many elements and redundant styles for font family, font size, etc. This plugin will clean up your pasted from the Word text without any side effects for other functionality. You can still insert elements and change styles, although this depends on your format filter allowances.
