## What it is
csvtk is a cross-platform command-line toolkit written in Go for manipulating CSV/TSV tabular data. It provides many subcommands for filtering, selecting, joining, and transforming tables, supporting gzipped and other compressed input and Unix pipes.

## Use cases
- manipulate csv files from the command line
- select columns by name in a tsv file
- filter and join csv tables in a shell pipeline
- replace excel click-work with automatable csv commands
- inspect and summarize large csv/tsv datasets quickly
- process gzipped csv files without decompressing
- clean up malformed quoted csv files

## When to choose
- you need fast, dependency-free CSV/TSV manipulation in shell scripts or pipelines
- you want column selection by name without writing Python/R scripts
- you work with compressed or streamed tabular data on Linux, macOS, or Windows

## When to avoid
- you need heavy spreadsheet-style GUI editing or pivot tables
- your data is not tabular (e.g., JSON, XML, or binary formats)
- you need complex statistical analysis better suited to pandas or R
