Here you go.

If you go here  PowerPoint Slide you will have a slide that has directions on how to update the data from  this web page.

So in this  example you write a Perl script that generates your data on a web page dynamicly. Then have a file simular to this
one pull the data and update your file.

I did not go into too much details on how to do this. Bad day and all, but if you think that you would want to try this I
can give you some tips.

Updated links which changed due to changes on my website.
