Round Tripping?

Logic: shows you how to use PowerPoint's html outputs to get rid of some corrupted parts of a presentation

This was something I discovered a while ago. I did find, however, that a couple of other people were using it already. 

Round Tripping (Shyam Pillai told me what it was called) is a way of hopefully getting bugs out of PowerPoint, and possibly errors.
 
It is simply a case of saving a presentation as html, and then re-opening it in PowerPoint. It uses clever technology that reverses a website to be re-opened in PowerPoint. It does reload all animations, plus embedded and linked objects... in fact everything I have tested it on.

CAVEAT
 
I cannot guarantee that it will work in every case. So, DO NOT delete your original PowerPoint file until you are convinced Round Tripping has brought back all of your objects, etc. Also note, it may affect the quality of your published images when you bring them back into PowerPoint. This may be important for printing.
 
So, how is it done?
 
First, is to save your presentation as a web page. Go to File, Save as Web Page. You will be given a file type option. I go for mht, as that creates a single file that I can later find and delete. If you don't have an mht option, go for htm.


save as web page

 
A box will pop up. First, click on the check box that says "Open published presentation in browser". We want that to occur when we are finished so we can grab the link back. Then, click on the Web Options button.
 
publish as web page dialogue box
 
Make sure you check the box that says "Show slide animation while browsing". Then click the "Browsers" tab at the very top.
 
web options dialogue box

 
My preference here is to make sure that I select the highest possible browser in the part about people who will be viewing the web page. Normally, you wouldn't really do this, as it would restrict how many people could see a web presentation. That's because not everyone has the latest version of Internet Explorer. However, I'm targeting a later browser in the hope it will cause less problems when I Round Trip back into later versions of PowerPoint. Now, I haven't tested this, but it's my current theory.
 
 
browsers tab
 
This is the result of selecting IE 6. There is no point in selecting the option for older browsers seen below as I don't intend anyone to see this one in a browser. It is simply for Round Tripping purposes.
 
select options
 
When we save our presentation, it will pop up in our browser. This is because we told it to open when publishes (first step). We copy this link, and go back to PowerPoint.
 
url address
 
We select the Open File dialogue box, and paste our url into the open section. We could navigate to where the file is stored, but I want to make sure I open the right file.
 
open dialogue box
 
When we open it, the presentation will be reversed back into a fully functional presentation, hopefully minus some problems.
 
Now, the really important bit. That is why I never recommend people muck with PowerPoint's html after it is published. You don't want to destroy something that then can't be reversed, or Round Tripped.
