This is a great tool thanks so much!

I tried it on my blog and it seems to be working quite nicely.

However, I am not seeing any syntax highlighting and it would be nice to have the code in something like grey boxes.

Here is a link to the notebook I used the script with: http://cgoliver.com/blog/2016/12/05/Intro_to_Python

Did it work as expected?

Thanks!

Carlos
