## What it is
csvq is a command line tool written in Go that lets you query and manipulate CSV files using a SQL-like language, including select, insert, update, and delete operations. It supports transactions, variables, cursors, temporary tables, an interactive shell, and multiple file formats such as TSV, LTSV, fixed-length, JSON, and JSON Lines.

## Use cases
- run SQL queries against CSV files from the command line
- update or delete records in a CSV file without a spreadsheet
- filter and join CSV data with SQL-like syntax
- process CSV files in batch scripts with transactions and variables
- query JSON Lines or TSV files with SQL
- interactively explore flat-file data in a shell
- share query scripts with coworkers across platforms

## When to choose
- you want a single dependency-free binary for ad-hoc CSV querying
- your data fits in memory at spreadsheet scale
- you need to update, insert, or delete CSV records, not just read them
- you want transactions, cursors, or variables in flat-file processing
- you need to handle multiple encodings like UTF-16 or Shift_JIS

## When to avoid
- you need to process very large datasets that exceed memory
- you need indexed or optimized query execution for speed
- you need a persistent database with concurrent access
- you need a library API rather than a CLI (though csvq-driver exists for Go)
