## What it is
JSONSelect is a CSS-like selector language for querying JSON documents, with a JavaScript reference implementation. It lets developers select nodes from JSON using familiar CSS-style syntax.

## Use cases
- query  documents with css-like selectors
- extract values from nested  structures
- filter  data streams efficiently
- find nodes in  by path patterns
- parse and select elements from  responses

## When to avoid
- you need actively maintained software with recent updates
- you need powerful querying like JSONPath or jq with advanced features
- you work outside JavaScript and need a mature implementation

## Facets
- artifact type: library
- maturity: abandoned
- function: parser, search-engine, developer-tools
- domain: developer-tools, parsers, apis
- platform: browser
- tags: css-selectors, -query, selector-language, javascript, nodejs
