JSONovich is a http://www.getfirefox.com/'>Firefox (and http://www.seamonkey-project.org/'>SeaMonkey) extension that pretty-prints JSON content of various types directly in a browser tab. It uses the browser's native JSON parser and a custom-built formatter to produce its output.

Normally, Firefox would either prompt to download or display as plain text any JSON sent with the correct application/json mime-type. JSONovich makes working with and debugging output from web services easier by formatting JSON nicely inside the browser.

FAQ

  • What's with the weird name?
    JSONovich is named after Pavement member Bob Nastanovich primarily because he seems like a swell guy.
  • And the logo?
    That's called an Ambihelical Hexnut, an optical illusion similar to the impossible torus that is the JSON logo.
