jsonfui is an interactive command-line JSON viewer. Examples

Download latest release from GitHub (does not require node.js).

Or, install via npm (requires node.js):

npm install -g jsonfui

To start jsonfui, pass a filename to it:

jsonfui /path/to/file.json

You can also read from stdin instead of a file:

curl -s https://api.github.com/users/adrianschneider/repos | jsonfui

You can also write to stdout with Enter:

# list repos, pick one, view on github
curl -s https://api.github.com/users/adrianschneider/repos | jsonfui | xargs open

When the application is open, you are in a vim-style tree viewer.

down, j: down
up, k: up
left, h: go back/up one level
right, l: view child node
<Enter>: send current selection to stdout and exit
y or c: copy current value to clipboard

/: search for string recursively

n: next search result at current depth
N: prev search result at current depth
