See my updated version:

• Fixes where amazon changed json node keys to to "yrTerm1Standard" .. etc and broke it entirely
• Also fixes the nano alignment issue

Note to anyone interested, these files are available for all AWS services that I can find.... But not all easily compatible/using the same node tree.

Just go to the AWS pricing page of your choice and view source, and find "data-model". You will find one file for every single PricingTable/Tab combo. For example MySQL standard deployments (single AZ) is:

http://a0.awsstatic.com/pricing/1/rds/mysql/pricing-standard-deployments.min.js

One small possible positive note -- it seems the URL/filenames themselves do follow a bit of a pattern. So it should be easy to generate them. If you had time and a little more powerful of a programming language, you could do great things.
