From the project README

An excerpt from the repository, fetched Nov 13, 2026.

Read the project’s introduction
rq NOTE: rq is in very low maintenance mode as my day job is taking up a lot of my time. I will try my best to merge pull requests but will not drive active development of this crate. NOTE: rq no longer ships with query support and a Javascript engine is not included; instead, it focuses exclusively on format transformation. You can still pipe into a runtime like node.js if you need Javascript evaluation. Please see this issue to discuss introducing a new query language. This is the home of the tool called rq (record query). It's a tool that's used for performing queries on streams of records in various formats. The goal is to make ad-hoc exploration of data sets easy without having to use more heavy-weight tools like SQL/MapReduce/custom programs. rq fills a similar niche as tools like awk or sed, but works with structured (record) data instead of text. It was created with love out of the best parts of Rust, and is distributed as a dependency-free binary on many operating systems and architectures. Quick links Installation — How to install rq. Tutorial — Learn rq from scratch. Protobuf — Configure Protobuf specifics. Development — Contribute to rq.

This is a really slick little utility! I'll definitely be adding it to my data munging grab bag. For those that deal with this sort of thing often, here are some similarly useful tools: ⠀ Really useful for generating table definitions and/or importing data from a csv to a variety of databases (bunch of other useful utilities in the repo as well): https://csvkit.readthedocs.io/en/latest/scripts/csvsql.html Similar to cq for querying a CSV file directly: http://harelba.github.io/q/ Not used often, but really handy when you come across a csv file it's designed for: http://colin.maudry.com/csvtool-manual-page/ Diff csv files: http://paulfitz.github.io/daff/ Can convert flatfiles between a bunch of different formats. Useful blunt tool to get things to and from csv files (among others): https://github.com/dflemstr/rq And for searching JSON: jq:

https://stedolan.github.io/jq/ gron: https://github.com/tomnomnom/gron Or use in2csv from csvkit or rq to get the JSON over to CSV and go from there.
