JSON Editor is a must-have editor for JSON data. In a clean, uncluttered and user-friendly interface, it allows you to quickly create, visualize, modify, validate, format and save your JSON documents.
Along with the included HTTP Client, is a powerful tool to inspect and debug your API endpoints.


• Edit JSON documents both in tree and raw modes.
• Syntax coloring, auto-indentation and line numbers.
• Validation of the JSON document.
• Highlight of the validation errors, along with a description of them.
• Make the JSON document human readable or compact, even if it is not entirely valid.
• Auto-detect if the document is human readable or compact, and preserve this format even if you edit in tree mode.
• Cut, copy, paste, delete and reorder tree nodes.
• Copy and paste for raw JSON strings.
• Undo and redo.
• Full support for "Find & Replace", both in tree and raw modes.
• Import and export property list (.plist) files.
• Support for pasting plist data, either from raw XML or from Xcode.
• Copy JSON tree nodes as Swift objects so you can use them in Xcode.
• Copy JSON tree nodes as Objective-C objects (both modern and classic syntax) so you can use them in Xcode.
• Copy JSON tree nodes as JSON Path strings.
• Copy JSON tree nodes as XML plist so you can paste them in Xcode or other text editor.
• "Add" and "Remove" buttons on the tree row which is selected or tracked by mouse.
• Ability to change the default font (both name and size). This font applies both to the JSON tree and to the raw editor.
• Ability to increase and decrease font size for better readability.
• Full screen support.
• Versions support.
• Services support.


• To open HTTP Client window choose "Window -> HTTP Client" menu item or use "Shift + Cmd + K" shortcut.
• HTTP Client allows you to easily perform HTTP requests. While its main purpose is to ease the fetch of JSON content from a server, it can be used to get or upload any content, including binary. The following HTTP verbs are supported: GET, POST, PUT, DELETE, HEAD.
• HTTP Client allows you to create folders to group the HTTP requests. Folders inside folders are supported, too! This feature is very handy to group the projects or APIs you're working with.
• HTTP Client automatically detects if response body is text or binary, and for binary responses it will show the preview of it, while allowing you save it to the desired directory.
• For response bodies which are text, you will have the option to beautify them as JSON and to open them in a new JSON Editor document.
• Both HTTP authentication (basic, digest) and Proxy authentication, with Keychain integration, are supported.
• OAuth 2.0 is supported for the following providers: bitly, Facebook, Foursquare, GitHub, Google, Instagram.
• Once you have added and setup an OAuth 2.0 authorization you can attach it to a HTTP request. Once this is done, JSON Editor will take care of refreshing and attaching access token to the HTTP request.

What's New

• JSON tree's row height now accomodates mult-line text - the rows are sized big enough to show all the lines. This option can be controlled from Preferences.
• Added "Edit -> Edit Value..." (Cmd + Shift + E) menu option. It works while you're in JSON tree mode and is very helpful especially when you want to edit long or multi-line texts.
• Added "Help -> Release Notes" menu item to be easier to check what's been implemented in previous versions of the application.

Bug fixing
• The "wrap around" HUD, used for text finding, is now properly centered in the window.
• Closing or saving a document while editing a key or value now works as expected - the edited key or value is saved to the file or discarded if it is invalid.
• Fixed a crash caused by opening plist files created using NSKeyedArchiver.
