Mac

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. For more info, visit OK JSON website: https://okjson.app. Privacy Policy: https://okjson.app/privacy-policy Terms of Service: https://okjson.app/terms-of-service
