I’m sorry, I was just trying to be helpful. Yes, I mean adding html tags.

For example
     if you use the pre tags
     you can do indents and it comes out looking
more like code. :-)

Oh yes, given what you’re saying I think it’s very likely that this is an OS issue (or WordPress issue), not InDesign.

WordPress 3.9 Has Built-in Support for Pasting from Microsoft Word

However, just to tease: Mike Rankin and I will be presenting a session at pepcon this June on the topic of Moving Content from InDesign to WordPress.

One of the main things we’ll be showing is how to export HTML directly from InDesign, clean it up with a script, and then just paste the raw HTML into WordPress.

Another thought: What happens if they copy from Word and paste into WordPress? (I believe WordPress has special filters that can convert Word formatting to HTML on the fly.)

I don’t know of any way to “push” InDesign edits back to an existing Word or Google doc other than the tools from Em Software.
