About:
Jello is a command-line utility that applies Python syntax to filter and manipulate JSON and JSON Lines data. It transforms complex JSON into a simplified, readable format, making it ideal for parsing API responses and system command outputs. The tool serves as a lightweight alternative to jq for users who prefer Python's syntax.

Key Features:

Uses Python syntax for JSON querying and manipulation
Supports both JSON and JSON Lines input formats
Outputs data in various formats including JSON, lists, and key-value pairs
Lightweight and easy to install via pip

Use Cases:

Parsing and filtering JSON output from command-line tools like curl or docker
Extracting specific values from API responses for shell scripting
Converting JSON data into a readable, plain-text format

Alternatives:

jq – jq uses its own DSL, while jello uses Python syntax, making it more accessible for Python developers.
python -m json.tool – The built-in Python module only pretty-prints JSON, whereas jello provides powerful querying and filtering capabilities.
