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.
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!

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 wanted a simple JSON reader that is local to my machine and will not push any sensitive content to the cloud. It read a chunky 6MB JSON file with no issues.
Exactly what the Dr. Ordered

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

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.
I should have started using this earlier!

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
Great app with attention to details
