## Description

Python JSONPath Next-Generation |Build Status| |PyPI|
=====================================================

A final implementation of JSONPath for Python that aims to be standard compliant, including arithmetic
and binary comparison operators, as defined in the original `JSONPath proposal`_.

This packages merges both `jsonpath-rw`_ and `jsonpath-rw-ext`_ and
provides several AST API enhancements, such as the ability to update or remove nodes in the tree.

About
-----

This library provides a robust and significantly extended implementation
of JSONPath for Python. It is tested with CPython 3.10 and higher.

This library differs from other JSONPath implementations in that it is a
full *language* implementation, meaning the JSONPath expressions are
first class objects, easy to analyze, transform, parse, print, and
extend.

Quick Start
-----------

To install, use pip:

.. code:: bash

    $ pip install --upgrade jsonpath-ng


Usage
-----

Basic examples:

.. code:: python

    $ python

    >>> from jsonpath_ng import jsonpath, parse

    # A robust parser, not just a regex. (Makes powerful extensions possible; see below)
    >>> jsonpath_expr = parse('foo[*].baz')

    #...

## AI interpretation — verify before relying

Parses and evaluates JSONPath expressions against JSON data, supporting standard operators, arithmetic comparisons, and AST manipulation for querying, updating, and filtering nested structures.

Verdict: Production-ready JSONPath implementation with zero security vulnerabilities, no external dependencies, and active maintenance. Suitable for applications requiring robust JSON querying with support for updates and filtering.
