Currently, I can use the space bar to preview a number of files such as .txt, .css, .html etc in Quick Look. I cannot, however, see the actual contents of a .json file.

Is there any possible way to see the contents of .json files through space bar preview in finder? (I'm Using OSX 10.8.4)


Download a release of qlstephen from Github, and load it into the /Library/Quicklook or ~/Library/QuickLook folder. Then, restart the Dock.

I use this all the time when previewing JSON files, and it works great.

    Worked perfectly. Thanks. One thing to add for terminal n008s like myself, restart the dock with the command "killall Dock". – Paul Aug 14 '13 at 16:53

also installable via

brew cask install qlstephen

    I had to first brew install caskroom/cask/brew-cask. Works great! – nialsh Oct 20 '15 at 21:50

    brew cask install qlstephen && killall Dock works for me, thanks! – Dmitry Kolesnikovich Aug 20 '18 at 14:56
  • I didn't even need to killall Dock on Mojave. Thanks – Ezekiel Victor Sep 9 '19 at 18:14

You can use the quicklook-json plugin. If you want to install it via homebrew, run

brew cask install quicklook-json

which requires a running

brew install caskroom/cask/brew-cask

if you never did that before.

  • Actually, vanilla brew search quicklook only returns quicklook-json as related to Json. – hectorpal Feb 10 '17 at 18:24

Macports provides an adequate port: sudo port install QLStephen.
