Project description


Jello Explorer

TUI to filter JSON and JSON Lines data with Python syntax

Here is a video of jellex in action:

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, a Viewer window displays on the right, and a Status window displays 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.

Use CTRL-Q to exit.

Note: Reserved key names that cannot be accessed using dot notation can be accessed via standard python dictionary notation. (e.g.["get"] instead of

Here is an example after running jellex twitterdata.json and modifying the query:

When you exit (CTRL-Q), you will be presented with your jello filter:

$ jellex twitterdata.json 
Your query:

jello '_[0].user'



The project is at a very simple working state. Here are some short-term plans:

  • Allow scrolling of the Viewer window
  • Allow switching to vi key bindings
  • Allow saving of the input file
  • Allow opening another file within the UI
  • Status bar showing the mode and filename, stats, etc.
