  "github_readme_excerpt": "# What is Miller?\n\n**Miller is like awk, sed, cut, join, and sort for data formats such as CSV, TSV, JSON, JSON Lines, and positionally-indexed.**\n\n# What can Miller do for me?\n\nWith Miller, you get to use named fields without needing to count positional\nindices, using familiar formats such as CSV, TSV, JSON, JSON Lines, and\npositionally-indexed.  Then, on the fly, you can add new fields which are\nfunctions of existing fields, drop fields, sort, aggregate statistically,\npretty-print, and more.\n\n![cover-art](./docs/src/coverart/cover-combined.png)\n\n* Miller operates on **key-value-pair data** while the familiar\nUnix tools operate on integer-indexed fields: if the natural data structure for\nthe latter is the array, then Miller\u0027s natural data structure is the\ninsertion-ordered hash map.\n\n* Miller handles a **variety of data formats**,\nincluding but not limited to the familiar **CSV**, **TSV**, and **JSON**/**JSON Lines**.\n(Miller can handle **positionally-indexed data** too!)\n\nIn the above image you can see how Miller embraces the common themes of\nkey-value-pair data in a variety of data formats.\n\n# Getting started\n\n[![deepwiki](https://deepwiki.com/badge.svg)](https://deepwiki.com/johnkerl/miller)\n\n* [Miller in 10 minutes](https://miller.readthedocs.io/en/latest/10min)\n* [A Guide To Command-Line Data Manipulation](https://www.smashingmagazine.com/2022/12/guide-command-line-data-manipulation-cli-miller)\n* [A quick tutorial on Miller](https://www.ict4g.net/adolfo/notes/data-analysis/miller-quick-tutorial.html)\n* [Miller Exercises](https://github.com/GuilloteauQ/miller-exercises)\n* [Tools to manipulate CSV files from the Command Line](https://www.ict4g.net/adolfo/notes/data-analysis/tools-to-manipulate-csv.html)\n* [www.togaware.com/linux/survivor/CSV_Files.html](https://www.togaware.com/linux/survivor/CSV_Files.html)\n* [MLR for CSV manipulation](https://guillim.github.io/terminal/2018/06/19/MLR-for-CSV-manipulation.html)\n* [Linux Magazine: Process structured text files w",
