Description and use

Miller (aka mlr) is a command‑line tool that brings the power of classic text‑processing utilities—awk, sed, cut, join, sort, etc.—to modern, name‑indexed data formats such as CSV, TSV, and tabular JSON. It lets you filter, transform, aggregate, and reshape structured records with concise, scriptable expressions, making large‑scale data wrangling fast and reproducible. Miller is open‑source, cross‑platform, and ideal for developers, data engineers, and analysts who need a lightweight yet powerful alternative to heavyweight ETL pipelines.
