xan: A Blazing-Fast CLI Tool for CSV Processing

xan is a command-line tool built in Rust for lightning-fast processing of massive CSV files (gigabytes!). Leveraging multithreading for parallelism, it easily handles tasks like previewing, filtering, slicing, aggregating, sorting, and joining CSV data. xan boasts a powerful expression language surpassing the speed of Python, Lua, or JavaScript for complex operations. Originally forked from xsv but extensively rewritten, xan caters to social science data analysis needs, including lexicometry, graph theory, and even web scraping. Installation is simple via cargo, Homebrew, pacman, Nix, or pre-built binaries.
