OK JSON is a fast, native JSON viewer for the Mac. Copy some JSON and press ⌘ V — or drop in a file — and it’s on screen as a clean, browsable tree. No browser tab, no upload, no waiting.
VIEW ANYTHING
• Paste from the clipboard, drag and drop, open files, or fetch JSON straight from a URL — even from a copied curl command.
• Browse documents in the Navigator, trace your location in the Path Bar, and zoom into any node to focus on just that part.
• Preview values with a tap of the Space bar: images, colors, timestamps, links, multiline text, and JSON hiding inside strings.
• JSON Lines and NDJSON open like regular documents, and OK JSON offers to repair broken JSON instead of just rejecting it.
FIND & QUERY
• Press ⌘ F to search the whole document.
• Process data with jq, built right in.
• Query with JSONPath, built right in.
• Compare two documents and get the difference as a JSON Patch.
EDIT
• Edit values in place, format the document, undo freely, and save changes back to the original file.
AUTOMATE
• Write scripts in JavaScript to transform JSON your way, with built-in APIs for text, files, alerts, jq, and more.
• Control OK JSON from AppleScript, the Raycast extension, or URL schemes.
• Preview JSON files right in Finder with the bundled Quick Look extension.
HISTORY
• Everything you view is saved locally and automatically. Organize items into folders, or let old ones clean themselves up.
PRIVATE BY DESIGN
• OK JSON works fully offline. Your JSON never leaves your Mac.
• No accounts, no analytics, no tracking of any kind. The app is sandboxed, and the only network requests are the ones you explicitly ask for.
NATIVE & FAST
• Built with AppKit for the Mac — quick to launch, light on memory, at home in light and dark mode.
• Localized in 12 languages.
QUICK LOOK
• OK JSON comes with a quick look extension for JSON files. You can view formatted JSON string with beautiful syntax highlight simply by tapping Spacebar in Finder.
OK JSON requires macOS 15 or later.

I should have started using this earlier!

This just solves the problem of "I need to view some JSON in a readable way without having a bunch of scratch buffers in my editor and setting 'JSON Mode' and then 'Prettify it'." With OK JSON, you just paste the JSON in and get everything. I was going through this annoying multi-step process every time I needed to manually navigate some JSON, and this tool solves all of my problems with a single step.It's fast. It's native. It just does what it's supposed to do and has already saved me so much time.
My go to JSON viewer

Well thought through with lots of nice features for inspecting JSON, such as paste, search, and the highlighting makes it easy to inspect JSON (looks nice too). The app serves my needs very well -- simple to use yet effective. Thanks!
Super useful

JSON makes my head hurt and this app has already been extremely helpful to make sense of it. It's simple to use and has an esthetically pleasing UI. Having it on my own machine is super nice as well. Thanks for this!
Great app with attention to details
foosball_p
This is an excellent app with a lot of anntetion to details. For example a service that allows any text to be sent to OK JSON.I miss having JSON Validation as well as display the content size in bytes / KB.Missing Raycast support like DevUtils supports. Please consider adding.Edit: Got the RayCast Integration working, thanks! Updated to 5 star. Still missing the JSON Validation feature which IntelliJ supports
Developer Response
You can paste in OK JSON with Raycast. Just go to main menu -> Help -> Integrations. You can contact me via email if this is not what you need.
