jq

What problem does it solve?

This Skill provides a powerful and efficient way to parse, filter, and transform JSON data, eliminating the need for manual inspection or complex scripting. It saves developers and data analysts significant time when working with API responses, configuration files, or log data.

Core Features & Use Cases

• JSON-Native Processing: Understands JSON structure for precise queries, avoiding the pitfalls of text-based tools like grep.
• Advanced Filtering & Transformation: Extract specific fields, reshape objects, iterate over arrays, and apply conditional logic to JSON data.
• Integration with Other Tools: Seamlessly pipes JSON output from other CLI tools (like ast-grep) for further analysis.
• Use Case: You receive a large JSON API response and only need to extract the name and email of users who are active. Use jq '.users[] | select(.status == "active") | {name, email}' to get exactly what you need in seconds.

Quick Start

Extract the version field from the package.json file. jq -r '.version' package.json
