Overview

OK JSON is a native and scriptable JSON viewer for your Mac. It’s fast, well-integrated with macOS, and fully offline.

Features

The notable features of OK JSON are:

  • Two-pane view: the tree structure in the Navigator and the formatted JSON string in the Editor.
  • View JSON from anywhere: the clipboard, files, URLs, cURL commands, drag-and-drop, Raycast, AppleScript, and URL Schemes.
  • Repair mode that fixes invalid JSON strings — trailing commas, single quotes, escaped strings, and more.
  • Built-in jq, JSONPath, and JSON Patch support, with saved filters and queries.
  • Find across keys and values, in the whole document or within a single node.
  • Edit values in place and save the changes back to the file.
  • Smart Quick Look: timestamps become dates, base64 images become pictures, colors get swatches, and JSON-in-a-string gets formatted.
  • Viewing History is automatically saved to a local database, with folders for keeping items permanently.
  • Custom Scripts written in JavaScript to further process JSON and text.
  • Support for opening JSON Lines , ndjson , and Property List  files.
  • Native user interface with beautiful syntax highlight themes, localized in 11 languages.
  • Offline and private: your documents are processed entirely on your Mac.

While OK JSON is a JSON viewer to the core, the Scripts feature also makes it a text-processing tool.
