JSON Viewer for macOS
A fast, native way to inspect and query JSON — with jq, JSONPath, and scripting built in. Fully offline: no browser tab, no upload, no account.


Everything you need to work with JSON
View it the moment you copy it, query it with jq, JSONPath, and scripts, and keep every byte on your Mac.


Paste anything. Even broken JSON.
From clipboard to structure in one keystroke — even when the JSON is broken.


jq, JSONPath, and scripts — built in.
Query and transform without leaving the app: jq, JSONPath, and JavaScript scripts


Everything stays on your Mac.
OK JSON has no analytics, no crash reporting, no telemetry of any kind; parsing, queries, and History live entirely on your Mac.
More than OK
What developers say once pasting, inspecting, and querying JSON with OK JSON becomes part of the daily routine.

This app does everything that I need. I especially like that it works offline and I therefore do not need to paste my JSON content in online formatters any more.
Great little JSON formatter

OK JSON quickly and beautifuly displays JSON payloads. Very easy to navigate and find keys and values. Very helpful for debugging APIs.
Great app for API work

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!
Super useful

I must have tried almost all apps and this one is my favorite when it comes to dealing with long JSON responses. I use it for development purposes every day now. Pros: - Native app - supports JS scripting - JSONPath - Raycast extension Cons: no cons! It's from the same developer who did Anybox, another very nice app. Definitely recommended!
An Amazing Nifty Tool to Work With JSON Data!
