csvkit
csvkit is a suite of command-line tools for working with CSV (Comma-Separated Values) files, written in Python. It provides utilities for viewing, converting, cleaning, and analyzing tabular data in CSV format, making it easier to handle data manipulation tasks directly from the terminal. The tools are designed to be efficient and integrate well with other Unix command-line tools like grep, awk, and sed.
Developers should learn csvkit when they need to quickly process, clean, or analyze CSV data without writing custom scripts, especially in data science, data engineering, or system administration workflows. It is particularly useful for tasks such as converting between CSV and other formats (e.g., JSON, Excel), filtering rows, sorting data, and performing basic statistical operations, saving time and reducing errors in manual data handling.
