Today I learned that you can use jq to convert JSON to CSV, which can be useful if you want to import some data into a spreadsheet.

As an example, here's how you can get a CSV of everyone who's in space right now:

$ curl -s http://api.open-notify.org/astros.json | \
  jq -r ".people[] | [.name, .craft] | @csv"

Which will give you this:

"Alexander Misurkin","ISS"
"Mark Vande Hei","ISS"
"Joe Acaba","ISS"
"Anton Shkaplerov","ISS"
"Scott Tingle","ISS"
"Norishige Kanai","ISS"
