I use vim for much of my text editing and sometimes want/need to format a copied (JSON but in plain unformatted) text string as JSON in vim.
Below is a quick guide to do doing so directly in vim and then adding it to your .vimrc configuration file for quick access.
Guide
In vim (normal mode) you can simply do:
:%!python -m json.tool
Adding as a command in .vimrc
You can add the following to your ~/.vimrc configuration file:
com! Jsonify %!python -m json.tool
To use this command in vim (normal mode), do:
:Jsonify
