+## JSON App Output
+
+`list`, `outdated` & `search` normally output tabular data, with a few fields
+for each app on its own row.
+
+`lookup` normally outputs fields as key-value pairs—one per line—in a contiguous
+block for each app, with a blank line between apps.
+
+If `--json` is supplied, these commands output a stream of JSON objects—one per
+app—each containing all fields provided by Apple for that app.
+
+Many of the JSON keys provided by Apple are poorly named, so they are mapped to
+better names by an algorithm.
+
+<!--editorconfig-checker-disable-->
+Mapped JSON keys are [sorted](
+  https://developer.apple.com/documentation/foundation/nsstring/compareoptions/numeric
+).
+<!--editorconfig-checker-enable-->
+
+Each JSON key should be unique within an object; if duplicate keys exist in an
+object, their relative ordering in the input is preserved in the output.
+
+If Apple renames or adds JSON keys, suboptimal JSON keys might be output until
+the mapping is updated.
+
+## JSON Config Output
+
+`config` normally outputs settings as key-value pairs, one per line.
+
+If `--json` is supplied, `config` outputs all settings in a single JSON object.
+
+Since the JSON keys are defined by mas, they are guaranteed to be unique &
+correct.

Within the hour, you’ll have everything off your mind and neatly organized—from routine tasks to your biggest life goals—and you can start focusing on what matters today.\\n\\n“Things offers the best combination of design and functionality of any app we tested, with nearly all the features of other power user applications and a delightful interface that never gets in the way of your work.”\\n—Wirecutter, The New York Times\\n\\n\\nKEY FEATURES\\n\\n• Your To-Dos\\nYour basic building block is the almighty To-Do—each a small step toward a great accomplishment. You can add notes, tag it, schedule it, and break it down into smaller steps.\\n\\n• Your Projects\\nCreate a Project for any big goal, then add the to-dos to reach it. Use headings to structure your list as you outline your plan. There’s also a place to jot down your notes, and a deadline to keep you on schedule.\\n\\n• Your Areas\\nCreate an Area for each sphere of your life, such as Work, Family, Finance, and so on. This keeps everything neatly organized, and helps you see the big picture as you set your plans in motion.\\n\\n• Your Plan\\nEverything on your schedule is neatly laid out in the Today and Upcoming lists, which show your to-dos and calendar events. Each morning, see what you planned for Today and decide what you want to do. The rest is down to you :)\\n\\n\\nMORE THINGS TO LOVE\\n\\nAs you dive deeper, you’ll find Things packed with helpful features. Here are just a few:\\n\\n• Reminders — set a time and Things will remind you.\\n• Repeaters — automatically repeat to-dos on a schedule you set.\\n• This Evening — a special place for your evening plans.\\n• Calendar integration — see your events and to-dos together.\\n• Tags — categorize your to-dos and quickly filter lists.\\n• Quick Entry — create to-dos from anywhere, as soon as the thought hits you.\\n• Quick Find — instantly locate to-dos, headings, or tags.\\n• Type Travel — jump from list to list with your keyboard; just start typing!\\n• Mail to Things — forward an email to Things; now it’s a to-do.\\n• And much more!\\n\\n\\nMADE FOR MAC\\n\\nThings is tailored to the Mac with deep system integrations as well. A great example is Quick Entry with Autofill: a shortcut that grabs content from other apps and adds it to Things for you, such as a link to a website or an email you want to get back to.\\n\\nYou can also enjoy a beautiful dark mode at sunset, connect your calendars, enable a Things widget, use your Mac’s Touch Bar, import from Reminders—Things can do it all! There’s even AppleScript support if you need powerful automation.\\n\\n\\nSTAY PRODUCTIVE ON THE GO\\n\\nThings has full-featured apps for iPhone, iPad, and Apple Watch as well (sold separately). All your devices sync seamlessly via our free Things Cloud service. It’s great to have everything at your fingertips when you need it!\\n\\n\\nAWARD-WINNING DESIGN\\n\\nMade in Stuttgart, with two Apple Design Awards to its name, Things is a fine example of German engineering: designed, not only to look fantastic, but to be perfectly functional as well. Every detail is thoughtfully considered, then polished to perfection.\\n\\n“It’s like the unicorn of productivity tools: deep enough for serious work, surprisingly easy to use, and gorgeous enough to enjoy staring at.”\\n—Apple\\n\\n\\nGET THINGS TODAY\\n\\nWhatever it is you want to accomplish in life, Things can help you get there.
