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 (outline) and text views.
• Multiple selection in tree mode. You can select multiple siblings and perform standard operations (i.e. copy, delete, drag and drop etc) on them.
• 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 the tree items.
• Copy and paste for raw JSON strings.
• Undo and redo.
• Easily embed selected items in Array or Object (dictionary).
• 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

Bug fixing
• Fixed a crash which happened when using "Open in JSON Document" from HTTP Client or "New JSON Document Containing Selection" from Services menu.
• Fixed a crash which happened when closing a window which had the search bar visible, on macOS 10.12 (Sierra).

Introduced in Version 1.15

• Multiple selection is now supported! You can select multiple siblings and perform the common operations on them.
• Added "Editor -> New Array from Selection" (Cmd + Shift + A) and "Editor -> New Object from Selection" (Cmd + Shift + D) menu items. These allow you to embed the selected items in an array or object (dictionary).
• The shortcut for "Add Row" is now Cmd + Return . This change was done because "Add Row" is probably the most used action in the application. A 2-keys shortcut provides the maximum for simplicity, and productivity as well.
• Preferences (Cmd + ,) now has an option to choose what happens when you press Return in tree editor: either the selected row will start editing or a new row will be created. The latter option is similar to Xcode's .plist editor, so some of you might find it more familiar.
• The entire text is shown upon hovering over "key" or "value" columns. This feature is especially useful for reviewing long texts.
• "Editor -> Expand All Children" has been renamed to "Recursively Expand Items" and "Editor -> Collapse All Children" to "Recursively Collapse Items".
• Added "Editor -> Expand Items" and "Editor -> Collapse Items".

Bug fixing
• Hitting Tab while in the "value" field will move the cursor to the "key" field of next row.
• Hitting Shift + Tab while in the "key" field will move the cursor to the "value" field of previous row.
