Build Status

Prettify/Minify/Query/Goto/Validate/Lint JSON plugin for Sublime Text 2 & 3


Install this sublime text 2/3 package via Package Control search for package: "Pretty JSON"

or manually install

  • cd <Packages directory> (for example on Mac it is ~/Library/Application\ Support/Sublime\ Text\ 2/Packages or ~/Library/Application\ Support/Sublime\ Text\ 3/Packages)
  • git clone


To prettify JSON, make selection of json (or else it will try to use full view buffer) and press keys:

  • Linux: ctrl+alt+j
  • Windows: ctrl+alt+j
  • OS X: cmd+ctrl+j

or through Command Palette Ctrl+Shift+P find "Pretty JSON: Format (Pretty Print) JSON" (you can search for part of it like 'pretty format')

If selection is empty and configuration entry use_entire_file_if_no_selection is true, tries to prettify whole file

If JSON is not valid it will be displayed in status bar of Sublime Text

Validate JSON

Using Command Palette Ctrl+Shift+P find "Pretty JSON: Validate" (you can search for partial string 'validate') this will validate selection or full file and will show in dialog if it's valid or invalid. In case of found errors view will jump to error and will highlight it

Compress / Minify JSON

Using Command Palette Ctrl+Shift+P find "Pretty JSON: Minify (compress) JSON" (you can search for part of it like 'json minify') this will make selection or full buffer as single line JSON which later you can use in command lines (curl/httpie) or somewhere else...

To map a key combination like Ctrl+Alt+M to the Minify command, you can add a setting like this to your .sublime-keymap file (eg: Packages/User/Default (Windows).sublime-keymap):

  { "keys": [ "ctrl+alt+m" ], "command": "un_pretty_json" }

Convert JSON to XML

Using Command Palette Ctrl+Shift+P search fo "Pretty JSON: JSON 2 XML" (you can search for part of it like '2XML') this will convert your selected JSON of full buffer to XML and replace syntax and buffer to XML output

./jQ query/filter usage



If on your machine "./jq" tool is available with ctrl+atl+shift+j you can run against your json. output will be opened in new view so you can once again apply jq on new buffer

You can find instructions of tool here:

Default configuration

use_entire_file_if_no_selection - true

indent - 2 int used for how many spaces to use for indent, replace it with value "\t" and tabs will be used instead

sort_keys - false

ensure_ascii - false

line_separator - ","

value_separator - ": " value separator in config, so if you need to get rid of extra space you can remove it with this param

keep_arrays_single_line - false if we need to re-structure arrays and make them single-line

max_arrays_line_length - 120 if array for example '["a", "b", 123213, ....]' length will reach max it will be kept multi-line (for beauty)

pretty_on_save - false do we need to automatically Pretty JSON on save

validate_on_save - true do we need validate JSON files on each save

Using tabs for indentation

You can change configuration key indent to string value "\t" or any other string

"indent" : "\t",

Be sure "Indent Using Spaces" is unchecked otherwise you will not see effect and ST2/3 will convert it back to spaces
