How can you copy a blog post into Word without having the formatting get messed up?

Not really. If I were you I would just take a screenshot and paste the image into word.

I agree with @omph. I don’t think there really is a way to do it without messing up the formatting. If you need to have it in word then think pasting in a screen shot is the only way to go, or you maybe use the print preview feature in your browser and print screen the preview pages.

maybe if you copied the html, but i’m not sue word recognises html formatting.

I don’t know about some particular blog post, but when I copy HTML pages into Word I have to adjust a bunch of table boundaries or take things out of tables, delete some elements, and change fonts and paragraph styles. It’s tedious, but it can be done. If you want the content in editable form instead of just an image (which you’d get by pasting a screen shot) you do have to fuss with it some. It won’t look like the blog.

You do know that you can save an HTML page as an HTML page, right? Just go up to File and choose ‘Save Page As’ and give it a name. You’ll get two things: the page format and all the things that go in it, saved in a little folder of the same name with ‘Files’ appended. You can see it by opening it in your browser.

Eaiest way is to paste it in as a graphic.

depends on what you want to do with it and what parts. You can save the page as html and open it in a web publsher app. Then have at it.
A program like word cant render all the tags and markup.
If you have MS OneNote, you can simply click a button and send it to OneNote.
Again, it depends on what you want to do with it.
