jq

jq is a lightweight and flexible command-line JSON processor developed by the jqlang community, currently at version 1.8.1 and available in five distinct releases. Designed for developers, system administrators, and data engineers who need to parse, filter, transform, and restructure JSON streams without writing custom scripts, the utility treats JSON as a data-flow language, enabling users to construct concise queries that extract specific keys, reshape nested objects, or aggregate arrays directly in the terminal. Typical use cases include preprocessing log files returned by REST APIs, sanitizing configuration payloads during CI/CD pipelines, generating condensed reports from large MongoDB exports, or validating and pretty-printing payloads in debugging sessions. Because it is distributed as a single self-contained executable with zero dependencies, jq integrates seamlessly into shell scripts, PowerShell automation, GitHub Actions, and Windows Task Scheduler jobs, making it equally valuable for ad-hoc interactive exploration and unattended batch operations. The program belongs to the Developer Tools category and supports standard input, file, and URL sources, while offering built-in functions for math, string manipulation, type conversion, and stream-oriented processing that keep memory usage low even on multi-gigabyte datasets. Version 1.8.1 refines error messages, improves Unicode handling, and adds several iterative operators, continuing a stable lineage that began with the initial public release and progressed through milestone builds that introduced streaming parsers, module systems, and comprehensive date-formatting facilities. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
