Extensions for JSONPath RW
Decision gist · record as of 2026-08-14
No—unless you are maintaining legacy code already using this package. The project is abandoned (last commit 2021-08-06, last release 2019-07-12) with no active maintenance or security updates. For new projects, use a maintained JSONPath library or consider alternatives like jsonpath-ng or jmespath that are actively developed and support modern Python versions.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low install friction with only two runtime dependencies (jsonpath-rw and pbr).
- However, the package is abandoned—last release was 2019-07-12 and last commit 2021-08-06—so no active maintenance or security updates should be expected.

What it is and what it does
jsonpath-rw-ext adds query and transformation extensions to the jsonpath-rw library, allowing you to extract, filter, sort, and perform arithmetic operations on JSON data using an extended JSONPath syntax. It provides shortcuts like len (get list length), sorted (return sorted lists), filter (select elements by condition), arithmetic operators (+, -, *, /), and string operations (sub for regex substitution, split for string splitting).
You use it by importing the module and calling parse() or match() functions with JSONPath expressions that include these extensions. The package is intended as a staging ground for features proposed upstream to jsonpath-rw; those that are accepted upstream may eventually be removed from here. It has low install friction but is no longer actively maintained, with the last release in 2019.
Use it for
- Extract and filter elements from nested JSON APIs using advanced query syntax beyond standard JSONPath.
- Perform calculations across JSON array elements, such as summing or combining values from multiple fields.
- Sort JSON objects by a field value or filter them by conditional expressions in a single query.
- Transform JSON strings using regex substitution or splitting operations within a JSONPath expression.
- Migrate from jsonpath-rw to a richer query language without rewriting your entire codebase.

More Text Processing packages
A drop-in replacement for Python's standard `re` module that adds advanced regex features like nested sets, fuzzy matching, lookaround in conditionals, and full Unicode case-folding while maintaining backward compatibility.
pyparsing provides a library for building text parsers directly in Python code using composable grammar classes, handling quoted strings, whitespace variation, and embedded comments without regex or lex/yacc.
Install it if you need to parse text or define grammars programmatically.
fonttools manipulates font files in multiple formats (TrueType, OpenType, AFM, Type 1, Mac-specific) and includes TTX, a tool to convert fonts to and from XML text format.
Install it if you need to read, write, or manipulate fonts programmatically or via the TTX command-line tool.
Docutils converts plaintext documentation in reStructuredText format into multiple output formats including HTML, XML, and LaTeX using a modular processing system.
RapidFuzz provides fast fuzzy string matching using Levenshtein Distance and related metrics, implemented mostly in C++ with Python bindings for rapid similarity scoring and approximate string matching.
Install it if you need fuzzy string matching; it's a solid replacement for FuzzyWuzzy with better licensing and performance.
tinycss2 parses CSS strings into token and block objects, and generates CSS strings from those objects, following the CSS Syntax Level 3 specification without enforcing specific properties or values.
Install it if your project requires CSS tokenization or syntax manipulation.
