A list of tools that generally make life easier when working with data.
Things I use and recommend
- jq is a lightweight and flexible command-line JSON processor. See Peter Koppstein’s A Stream oriented Introduction to jq for the missing manual.
- csvkit is a suite of command-line tools for converting to and working with CSV, the king of tabular file formats.
- gron gron transforms JSON into discrete assignments to make it easier to grep for what you want and see the absolute ‘path’ to it. It eases the exploration of APIs that return large blobs of JSON but have terrible documentation. Its primary purpose is to make it easy to find the path to a value in a deeply nested JSON blob when you don’t already know the structure; much of jq’s power is unlocked only once you know that structure.
yq a lightweight and portable command-line YAML processor. yq uses jq like syntax but works with yaml files as well as json.
I find it useful to work with
terraform show -json ~/tmp/tfplan.
- q is a command line tool that allows direct execution of SQL-like queries on CSVs/TSVs (and any other tabular text files). * vscode-edit-csv is an extension for Visual Studio Code that allows you to edit csv files with an Excel-like table UI.
Things I haven’t tried yet
- Data Retriever automates the first steps in the data analysis pipeline by downloading, cleaning, and standardizing datasets, and importing them into relational databases, flat files, or programming languages.

- immudb is a database with built-in cryptographic proof and verification. It can track changes in sensitive data and the integrity of the history will be protected by the clients, without the need to trust the server. It can operate as a key-value store or as relational database (SQL).
- lux is a Python library that facilitate fast and easy data exploration by automating the visualization and data analysis process. By simply printing out a dataframe in a Jupyter notebook, Lux recommends a set of visualizations highlighting interesting trends and patterns in the dataset. Visualizations are displayed via an interactive widget that enables users to quickly browse through large collections of visualizations and make sense of their data. Blog. Demo

During a migration, Reshape ensures both the old and new schema are available at the same time, allowing you to gradually roll out your application.
- SQLime is an online SQLite playground for debugging and sharing SQL snippets. Like SQLFiddle from back in the day.
Results from the survey about LibreOffice Calc in 2021 is most interesting for the alternative toolkit of its surveyed users. I need to try some of these!
Results from the survey about LibreOffice Impress in 2022 is interesting for the same reason. Avoid PowerPoint. Prefer text-driven tools.

- WP2TXT extracts text and category data from Wikipedia dump files (encoded in XML / compressed with Bzip2), removing MediaWiki markup and other metadata.
- Deequ is a library built on top of Apache Spark for defining “unit tests for data”, which measure data quality in large datasets. Most applications that work with data have implicit assumptions about that data, e.g., that attributes have certain types, do not contain NULL values, and so on. If these assumptions are violated, your application might crash or produce wrong outputs. The idea behind deequ is to explicitly state these assumptions in the form of a “unit-test” for data, which can be verified on a piece of data at hand. If the data has errors, we can “quarantine” and fix it, before we feed it to an application.
- Soda Core is a free, open-source, command-line tool that enables you to use the Soda Checks Language to turn user-defined input into aggregated SQL queries.
