## What it is
Hjson is a syntax extension to JSON that makes configuration files easier for humans to read and edit, adding comments, optional commas, quoteless strings, and multiline strings. It provides parsers and serializers implemented across many languages that convert between Hjson and standard JSON.

## Use cases
- write config files with comments in json
- parse hjson to json
- avoid comma syntax errors in json configs
- human-editable json format
- convert hjson config to standard json
- multiline strings in json config

## When to choose
- you need JSON-compatible config files that humans frequently read and edit
- you want inline comments and relaxed syntax in configuration data
- you need implementations across multiple languages with a common spec

## When to avoid
- you need strict, machine-generated JSON with no tolerance for comments or relaxed syntax
- your tooling only accepts standard JSON parsers
- you need a full configuration management system rather than a data format

## Facets
- artifact type: library
- maturity: maintenance
- function: serialization, parser, configuration-management, developer-tools
- domain: developer-tools, files, apis
- platform: cross-platform, python, go, rust, jvm, dotnet, php, lua
- tags: json, hjson, config-format, human-readable, comments, multi-language, nodejs
