TUI to filter JSON and JSON Lines data with Python syntax
Here is a video of jellex
in action: https://youtu.be/-oR0yZ7JaO8
Jello Explorer (jellex
) is a Text User Interface program to interactively process JSON and JSON Lines at the console using Python syntax. jellex
uses jello
on the back-end to run the queries.
Jello Explorer can be installed via pip
:
pip install jellex
jellex file.json
An Editor window displays on the left and a Viewer window displays on the right. Schema and Status windows display on the bottom.
The Editor window uses standard EMACS key bindings and allows you to type your Python syntax query. _
is the sanitized JSON from the file presented as a python dict or list of dicts. You can use dot notation or traditional python bracket notation to access key names.
As you modify your query, the Viewer window will update with the latest results. If there are any errors in the query (syntax errors, etc.), they will be displayed in the Status window at the bottom.
Tab completions are available for current context list indicies and key names.
Use CTRL-\
to toggle the focus between the Editor, Viewer, and Schema windows.
Use CTRL-S
to toggle the Schema window.
Use CTRL-Q
or CTRL-C
to exit.
Note: Reserved key names that cannot be accessed using dot notation can be accessed via standard python dictionary notation. (e.g.
_.foo["get"]
instead of_.foo.get
)
Here is an example after running jellex twitterdata.json
and modifying the query:
When you exit (CTRL-Q
or CTRL-C
), you will be presented with your jello
filter:
$ jellex twitterdata.json
Your query:
jello '_[0].user'
$
