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. KEY FEATURE - JSON EDITOR ? Edit JSON documents both in tree and text modes. ? Multiple selection in tree mode - you can select multiple siblings and perform standard operations (i.e. copy, 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 ? Cut, copy, paste, delete and reorder the tree items. ? Copy & paste for JSON text. ? Undo & redo. ? Easily embed selected items in Array or Object (dictionary). ? Full support for Find & Replace, both in tree and text modes. ? In tree mode you can choose where the Find (and Replace) will take place: in "Key" column or "Value" column or both. The option which controls which columns will be searched is available by clicking the "search" image in the find bar (Command + F) and then accessing the options from "Find In" submenu. ? Find also lets you configure where in the JSON's keys and values to look for matches: "Contains", "Equals To", "Starts With" and "Ends With". ? Import and export property list (.plist) files. ? Support for pasting plist data, either from XML text or from Xcode. ? Copy JSON nodes as Swift objects so you can use them in Xcode. ? Copy JSON nodes as Objective-C objects (both modern and classic syntax) so you can use them in Xcode. ? Copy JSON nodes as JSON Path strings. ? Copy JSON 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 tracked by mouse. ? Ability to change the default font (both font family and size)- this font applies both to the JSON tree and to the text editor. ? Ability to increase and decrease font size for better readability. ? Full screen support. ? Versions support. ? Services support. ? Detect when the JSON document is changed by another application. In Preferences (Command + ,) -> "General" tab, you have the ability to customize what to do when this happens: "Keep JSON Editor's version" or "Ask how to resolve" or "Update to modified version". ? Double click on one of JSON tree's column separators to resize the corresponding column so the largest text in that column will be visible. KEY FEATURE - HTTP CLIENT ? To open HTTP Client window choose "Window -> HTTP Client" (Shift + Command + K) ? 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. ? You can 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. ? Automatically detects if response body is text or binary, and for binary responses will shows its preview, while also allowing you save it to the desired file. ? 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 also supported. In addition to the built-in providers (bitly, Facebook, Foursquare, GitHub, Google, Instagram) you may add your custom ones, too. ? Once you have added and setup an OAuth 2.0 authorization you can attach it to a HTTP request - JSON Editor will take care of refreshing and attaching access token to the HTTP request.
