Master list of contrib modules? Does there exist an updated master list of contrib modules in some easily parsed format (csv, json, xml ... whatever) that I can use for quick reference to see active full projects (not sandbox)? 

I'm particularly interested in a list of project names and their machine names. I'm working on a custom module that may turn into a contrib module and I'd like to make sure my project name and machine name aren't already in use.

I know I can search here:

https://www.drupal.org/project/project_module

But it'd save time if there was a list I could quickly reference. A quick Google search yielded no usable results in the first few pages.
It will be a pretty big list, you could get all packages known by composer which should contain pretty much everything

composer show drupal/* --all
