In this tutorial, you will learn howto use brew (aka Homebrew) to install ‘jq’ on Mac OS. Brew is an open source alternative to Apple App Store to install any MacOS program or application.

What is JQ?
jq is a lightweight and flexible command-line JSON processor that can be run as a command from bash Terminal.

jq is like sed for JSON data – you can use it to slice and filter and map and transform structured data with the same ease that sed, awk, grep let you play with text.

jq syntax supports advanced features on JSON like while loop, filters, types and Values, builtin operators and functions, conditionals and comparisons, regular expressions (PCRE), math, I/O, streaming, assignment, modules and pretty prints JSON on Terminal or bash with syntax highlighting

How does ‘jq’ work?
A jq program is a “filter”: it takes an input, and produces an output. There are a lot of builtin filters for extracting a particular field of an object, or converting a number to a string, or various other standard tasks.

jq filters run on a stream of JSON data. The input to jq is parsed as a sequence of whitespace-separated JSON values which are passed through the provided filter one at a time. The output(s) of the filter are written to standard out, again as a sequence of whitespace-separated JSON data.

You can also combine Filters in various ways. For e.g. you can pipe the output of one filter into another filter, or collect the output of a filter into an array. You can also use jq with other tools (such as curl) or convert JSON to other formats such as CSV.

Is brew/Homebrew safe?
Brew is a open source package manager (that runs as a command from and uses your Mac’s wifi / internet to download and install supported programs). Using Homebrew, anyone can install thousands of softwares and apps on Macbook Pro, Macbook Air, Mac Mini, iMac, Mac Pro or any PC running MacOS etc. Key alternatives to application installers on Mac OS X include AppStore, Macports, PKG file or DMG files, Nix, Mac Ports to name a few.

Supported versions:
These installation instructions will work on all latest / core versions of MacOS (including Snow Leopard, Mountain Lion, Mavericks, Yosemite, El Capitan, Sierra, High Sierra, Mojave, Catalina, Big Sur, plus MacOS Server)
