## What it is
yq is a lightweight, portable command-line processor for YAML, JSON, XML, CSV, TOML, HCL, INI, and properties files, using jq-like syntax. Written in Go, it ships as a dependency-free binary for reading, updating, merging, and converting between structured data formats.

## Use cases
- extract values from yaml files in shell scripts
- convert json to yaml from the command line
- update kubernetes manifest files in place
- merge multiple yaml config files
- query and edit toml or xml files with jq-like syntax
- process csv and properties files in ci pipelines

## When to choose
- you need a single dependency-free binary for structured data manipulation
- you want jq-style expressions but for YAML and other formats
- you're editing config files in CI/CD pipelines or shell scripts

## When to avoid
- you need full jq feature coverage for complex JSON programs
- you prefer a library API inside a programming language rather than a CLI
- you need schema validation of YAML documents
