Plutext's docXwave extension can:

Importing is especially useful if your document contains tables or images, because copy/pasting from Word leaves them out. Adding the document as an attachment isn't the answer, because that doesn't bring the power of Wave to bear on the doc at all.

There are 3 ways to import a document:

  1. Install the extension, then click the toolbar icon to add the robot to an existing Wave, or
  2. The manual way: add docxwave@appspot.com to your contacts, then create a new wave and add that contact to it.
  3. Install the extension, then click the 'New Wave' drop down and choose 'Import Document'

When you add the robot to your wave, a File Upload form should appear in response. If the form doesn't appear, try removing the robot from the wave and re-adding it.

Once you've gone through the process, you should see your document added.

To export from Wave, type !docx in the blip you want to export (this can be any old blip - it doesn't have to be one created by importing). That text will be replaced with a link to from which you can download the resulting .docx file
