Installation
Install this sublime text 2/3 package via Package Control search for
package: "Pretty JSON" or manually install cd
(for example on Mac it is ~/Library/Application\ Support/Sublime
Text\ 2/Packages or ~/Library/Application\ Support/Sublime\ Text
3/Packages) git clone SublimePrettyJson.git
Usage
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:
jQ lightweight and flexible command-line JSON processor.
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
