do you have any tools to delete all unused styes in word document?

This does not describe Word 365 for Mac - the menu items, etc. simply do not match. I finally found the Templates under Tools in the menu bar and more or less was able to save a template from one document then Attach it and use in another.But it was trial and error.

Great help, got me through

I have word 2007. I could not manage to do.

Thank you. In Word 2016 for Mac I was able to do it by starting from Tools -> Templates and Add-Ins -> Organizer and then follow your instructions.

This made life easier, thank you

THANKS! Phew

I found a much easier way (it works for Word 2016, I don't know for earlier versions of Word):
- In the document you have created your styles and headings, go to the 'Design' tab and click the downward arrow on the style sets. Then choose 'Save as a New Style Set'. A popup window will open to save the style set as a Word Template (*.dotx). Type in a name for the template style set and save it.
- In the new document where you want to use these styles, go again to the 'Design' tab and click the downward arrow on the styles sets. Then choose your saved template style set under 'Custom'. The style set will apply to your headings (if included in the template) and you can choose those styles for any paragraph.

thanks for the help!
