jq

jq is the indispensable command-line JSON processor: it slices, filters, maps, and transforms structured data with a concise, declarative syntax.

This is your go-to utility for JSON manipulation in the terminal. Think of jq as `sed` or `awk` for structured data, but operating directly on JSON values (not just lines of text). It's a lightweight, functional, domain-specific language designed for high-efficiency data handling. Built in portable C, it boasts zero runtime dependencies, making deployment fast and reliable across Linux, macOS, and Windows. Use it to extract specific fields (e.g., `.results[].id`), perform complex data transformations, or simply pretty-print API responses piped from `curl` into your shell scripts and DevOps pipelines.
