## What it is
xsv is a fast, composable command-line toolkit written in Rust for indexing, slicing, analyzing, splitting, and joining CSV files. It offers simple subcommands like stats, join, sort, and search with an emphasis on performance. The project is now unmaintained, with qsv and xan recommended as successors.

## Use cases
- slice and index large csv files from the command line
- compute column statistics on a csv
- join two csv files quickly
- split a big csv into chunks
- build frequency tables of csv columns
- filter csv rows with a regex

## When to choose
- you need a fast, scriptable csv tool and are fine with an unmaintained project
- you want simple composable unix-style csv commands
- you need constant-time slicing via csv indexing

## When to avoid
- you want an actively maintained tool - use qsv or xan instead
- you need a GUI or spreadsheet-like interface
- you work with formats other than csv/tsv

## Facets
- artifact type: cli-tool
